The desktop includes these panels:
-
Current Folder — Access your files.
-
Command Window — Enter commands at the command line, indicated by the prompt (>>).
-
Workspace — Explore data that you create or import from files. 探索数据
As you work in MATLAB, you issue commands that create variables and call functions. For example, create a variable named a by typing this statement at the command line:
a = 1
MATLAB adds variable a to the workspace and displays the result in the Command Window.
a =
1
Create a few more variables.
b = 2
b =
2
c = a + b
c =
3
d = cos(a)
d =
0.5403
When you do not specify an output variable, MATLAB uses the variable ans, short for answer, to store the results of your calculation.当你不指定输出变量时，matlab使用变量ans（answer的简称）来存储计算的结果。
sin(a)
ans =
0.8415
If you end a statement with a semicolon, MATLAB performs the computation, but suppresses the display of output in the Command Window. 输入；抑制输出结果的展示。
e = a*b;
You can recall previous commands by pressing the up- and down-arrow keys, ↑ and ↓. Press the arrow keys either at an empty command line or after you type the first few characters of a command. For example, to recall the command b = 2, type b, and then press the up-arrow key.
按up或down键来调用先前的命令。
Matrices and Arrays
MATLAB is an abbreviation for "matrix laboratory."（matrix laboratory矩阵实验室） While other programming languages mostly work with numbers one at a time, MATLAB® is designed to operate primarily on whole matrices and arrays.
All MATLAB variables are multidimensional arrays, no matter what type of data. A matrix is a two-dimensional array often used for linear algebra.
所有的matlalb变量都是多维数组，不论是何种数据类型。一个matrix是二维数组。
Array Creation
To create an array with four elements in a single row, separate the elements with either a comma (,) or a space.（使用逗号或空格分离。
a = [1 2 3 4]
returns
a =
1 2 3 4
This type of array is a row vector.
To create a matrix that has multiple rows, separate the rows with semicolons.分离每个row用；
a = [1 2 3; 4 5 6; 7 8 10]
a =
1 2 3
4 5 6
7 8 10
Another way to create a matrix is to use a function, such as ones, zeros, or rand. For example, create a 5-by-1 column vector of zeros.
z = zeros(5,1)
z =
0
0
0
0
0
Matrix and Array Operations
MATLAB allows you to process all of the values in a matrix using a single arithmetic operator or function.
matlab允许你在matrix中用单一算术运算符处理所有的值。
a + 10
ans =
11 12 13
14 15 16
17 18 20
sin(a)
ans =
0.8415 0.9093 0.1411
-0.7568 -0.9589 -0.2794
0.6570 0.9894 -0.5440
To transpose a matrix, use a single quote ('): 用'转置矩阵
a'
ans =
1 4 7
2 5 8
3 6 10
You can perform standard matrix multiplication, which computes the inner products between rows and columns, using the * operator. For example, confirm that a matrix times its inverse returns the identity matrix:
p = a*inv(a)
p =
1.0000 0 -0.0000
0 1.0000 0
0 0 1.0000
Notice that p is not a matrix of integer values. MATLAB stores numbers as floating-point values, and arithmetic operations are sensitive to small differences between the actual value and its floating-point representation. You can display more decimal digits using the format command:
format long p = a*inv(a)
p =
1.000000000000000 0 -0.000000000000000
0 1.000000000000000 0
0 0 0.999999999999998
Reset the display to the shorter format using
format short
format affects only the display of numbers, not the way MATLAB computes or saves them.
To perform element-wise multiplication rather than matrix multiplication, use the .* operator:
实现矩阵按元素逐位相乘而不是矩阵乘法，使用.*。
p = a.*a
p =
1 4 9
16 25 36
49 64 100
The matrix operators for multiplication, division, and power each have a corresponding array operator that operates element-wise. For example, raise each element of a to the third power:做幂运算
a.^3
ans =
1 8 27
64 125 216
343 512 1000
Concatenation
Concatenation is the process of joining arrays to make larger ones. In fact, you made your first array by concatenating its individual elements. The pair of square brackets [] is the concatenation operator.事实上，你做的第一个array，[1,2,3]就是连接单个的元素而成为了array。[]是连接运算符
A = [a,a]
A =
1 2 3 1 2 3
4 5 6 4 5 6
7 8 10 7 8 10
Concatenating arrays next to one another using commas is called horizontal concatenation. Each array must have the same number of rows. Similarly, when the arrays have the same number of columns, you can concatenate vertically using semicolons.
使用逗号连接的叫水平连接，每个array必须有相同的行数。垂直连接使用分号。
A = [a; a]
A =
1 2 3
4 5 6
7 8 10
1 2 3
4 5 6
7 8 10
Complex Numbers
Complex numbers have both real and imaginary parts, where the imaginary unit is the square root of –1.
sqrt(-1)
ans = 0.0000 + 1.0000i
To represent the imaginary part of complex numbers, use either i or j.
c = [3+4i, 4+3j; -i, 10j]
c = 3.0000 + 4.0000i 4.0000 + 3.0000i 0.0000 - 1.0000i 0.0000 +10.0000i
Array Indexing
Every variable in MATLAB® is an array that can hold many numbers. When you want to access selected elements of an array, use indexing.
For example, consider the 4-by-4 magic square A:（参考：http://zh.wikipedia.org/wiki/%E5%B9%BB%E6%96%B9）
A = magic(4)
A =
16 2 3 13
5 11 10 8
9 7 6 12
4 14 15 1
There are two ways to refer to a particular element in an array. The most common way is to specify row and column subscripts, such as
A(4,2)
ans =
14
Less common, but sometimes useful, is to use a single subscript that traverses down each column in order:
A(8)
ans =
14
Using a single subscript to refer to a particular element in an array is called linear indexing.使用单一的下标叫线性索引。
If you try to refer to elements outside an array on the right side of an assignment statement, MATLAB throws an error.
test = A(4,5)
Attempted to access A(4,5); index out of bounds because size(A)=[4,4].
在赋值表达式的右边索引超界会抛出错误。
However, on the left side of an assignment statement, you can specify elements outside the current dimensions. The size of the array increases to accommodate the newcomers.
A(4,5) = 17
A =
16 2 3 13 0
5 11 10 8 0
9 7 6 12 0
4 14 15 1 17
在赋值表达式左边索引超界不会抛出错误，array的size会增加以适应新来者。
To refer to multiple elements of an array, use the colon operator, which allows you to specify a range of the form start:end. For example, list the elements in the first three rows and the second column of A:
使用start:end（包括end）来表示一个range。
A(1:3,2)
ans =
2
11
7
The colon alone, without start or end values, specifies all of the elements in that dimension. For example, select all the columns in the third row of A:
只有：，没有start和end，表示所有
A(3,:)
ans =
9 7 6 12 0
The colon operator also allows you to create an equally spaced vector of values using the more general form start:step:end.
B = 0:10:100
B =
0 10 20 30 40 50 60 70 80 90 100
If you omit the middle step, as in start:end, MATLAB uses the default step value of 1.
Workspace Variables
The workspace contains variables that you create within or import into MATLAB® from data files or other programs. For example, these statements create variables A and B in the workspace.
A = magic(4); B = rand(3,5,2);
You can view the contents of the workspace using whos.
whos
Name Size Bytes Class Attributes A 4x4 128 double B 3x5x2 240 double
The variables also appear in the Workspace pane on the desktop.
Workspace variables do not persist after you exit MATLAB. Save your data for later use with the savecommand,
save myfile.mat
Saving preserves the workspace in your current working folder in a compressed file with a .mat extension, called a MAT-file.
To clear all the variables from the workspace, use the clear command.
Restore data from a MAT-file into the workspace using load.
load myfile.mat
Character Strings
A character string is a sequence of any number of characters enclosed in single quotes. You can assign a string to a variable.
myText = 'Hello, world'; 单引号表示字符串，双引号错误。
If the text includes a single quote, use two single quotes within the definition.
otherText = 'You''re right'
otherText = You're right
myText and otherText are arrays, like all MATLAB® variables. Their class or data type is char, which is short for character.
mytext和othertext是同所有的matlab变量一样，是array。它们的data type是char。
whos myText
Name Size Bytes Class Attributes myText 1x12 24 char
You can concatenate strings with square brackets, just as you concatenate numeric arrays.
用【】连接字符串，仅仅像连接numeric arrays一样。
longText = [myText,' - ',otherText]
longText = Hello, world - You're right
To convert numeric values to strings, use functions, such as num2str or int2str.
f = 71; c = (f-32)/1.8; tempText = ['Temperature is ',num2str(c),'C']
tempText = Temperature is 21.6667C
Calling Functions
MATLAB® provides a large number of functions that perform computational tasks. Functions are equivalent to subroutines or methods in other programming languages.
To call a function, such as max, enclose its input arguments in parentheses:
A = [1 3 5]; max(A);
If there are multiple input arguments, separate them with commas:
B = [10 6 4]; max(A,B);
函数多个参数用逗号分隔。
（使用max 矩阵维度必须一致）。
结果：
ans =
10 6 5
Return output from a function by assigning it to a variable:
maxA = max(A);
When there are multiple output arguments, enclose them in square brackets:
[maxA,location] = max(A);
Enclose any character string inputs in single quotes:
disp('hello world');
To call a function that does not require any inputs and does not return any outputs, type only the function name:
clc
The clc function clears the Command Window.
调用一个函数，没有任何input和output，仅仅打函数名字即可。
2-D and 3-D Plots
Line Plots
To create two-dimensional line plots, use the plot function. For example, plot the value of the sine function from 0 to 
:
x = 0:pi/100:2*pi; y = sin(x); plot(x,y)
You can label the axes and add a title.
xlabel('x')
ylabel('sin(x)')
title('Plot of the Sine Function')
By adding a third input argument to the plot function, you can plot the same variables using a red dashed line.
plot(x,y,'r--')
The 'r--' string is a line specification. Each specification can include characters for the line color, style, and marker. A marker is a symbol that appears at each plotted data point, such as a +, o, or *. For example,'g:*' requests a dotted green line with * markers.
Notice that the titles and labels that you defined for the first plot are no longer in the current figure window. By default, MATLAB® clears the figure each time you call a plotting function, resetting the axes and other elements to prepare the new plot.
每次调用plot都会清除以前的配置。
To add plots to an existing figure, use hold.
x = 0:pi/100:2*pi;
y = sin(x);
plot(x,y)
hold on
y2 = cos(x);
plot(x,y2,'r:')
legend('sin','cos')
Until you use hold off or close the window, all plots appear in the current figure window.
3-D Plots
Three-dimensional plots typically display a surface defined by a function in two variables, z = f(x,y) .
To evaluate z, first create a set of (x,y) points over the domain of the function using meshgrid.
[X,Y] = meshgrid(-2:.2:2); Z = X .* exp(-X.^2 - Y.^2);
Then, create a surface plot.
surf(X,Y,Z)
Both the surf function and its companion mesh display surfaces in three dimensions. surf displays both the connecting lines and the faces of the surface in color. mesh produces wireframe surfaces that color only the lines connecting the defining points.
Subplots
You can display multiple plots in different subregions of the same window using the subplot function.
For example, create four plots in a 2-by-2 grid within a figure window.
t = 0:pi/10:2*pi;
[X,Y,Z] = cylinder(4*cos(t));
subplot(2,2,1); mesh(X); title('X');
subplot(2,2,2); mesh(Y); title('Y');
subplot(2,2,3); mesh(Z); title('Z');
subplot(2,2,4); mesh(X,Y,Z); title('X,Y,Z');
The first two inputs to the subplot function indicate the number of plots in each row and column. The third input specifies which plot is active.
Programming and Scripts
The simplest type of MATLAB® program is called a script. A script is a file with a .m extension that contains multiple sequential lines of MATLAB commands and function calls. You can run a script by typing its name at the command line.
Sample Script
To create a script, use the edit command,
edit plotrand
This opens a blank file named plotrand.m. Enter some code that plots a vector of random data:
n = 50; r = rand(n,1); plot(r)
Next, add code that draws a horizontal line on the plot at the mean:
m = mean(r);
hold on
plot([0,n],[m,m])
hold off
title('Mean of Random Uniform Data')
Whenever you write code, it is a good practice to add comments that describe the code. Comments allow others to understand your code, and can refresh your memory when you return to it later. Add comments using the percent (%) symbol.
% Generate random data from a uniform distribution
% and calculate the mean. Plot the data and the mean.
n = 50; % 50 data points
r = rand(n,1);
plot(r)
% Draw a line from (0,m) to (n,m)
m = mean(r);
hold on
plot([0,n],[m,m])
hold off
title('Mean of Random Uniform Data')
Save the file in the current folder. To run the script, type its name at the command line:
plotrand
You can also run scripts from the Editor by pressing the Run button, 
.
Loops and Conditional Statements
Within a script, you can loop over sections of code and conditionally execute sections using the keywordsfor, while, if, and switch.
For example, create a script named calcmean.m that uses a for loop to calculate the mean of five random samples and the overall mean.
nsamples = 5;
npoints = 50;
for k = 1:nsamples
currentData = rand(npoints,1);
sampleMean(k) = mean(currentData);
end
overallMean = mean(sampleMean)
Now, modify the for loop so that you can view the results at each iteration. Display text in the Command Window that includes the current iteration number, and remove the semicolon from the assignment tosampleMean.
for k = 1:nsamples iterationString = ['Iteration #',int2str(k)]; disp(iterationString) currentData = rand(npoints,1); sampleMean(k) = mean(currentData) end overallMean = mean(sampleMean)
When you run the script, it displays the intermediate results, and then calculates the overall mean.
calcmean
Iteration #1
sampleMean =
0.3988
Iteration #2
sampleMean =
0.3988 0.4950
Iteration #3
sampleMean =
0.3988 0.4950 0.5365
Iteration #4
sampleMean =
0.3988 0.4950 0.5365 0.4870
Iteration #5
sampleMean =
0.3988 0.4950 0.5365 0.4870 0.5501
overallMean =
0.4935
In the Editor, add conditional statements to the end of calcmean.m that display a different message depending on the value of overallMean.
if overallMean < .49
disp('Mean is less than expected')
elseif overallMean > .51
disp('Mean is greater than expected')
else
disp('Mean is within the expected range')
end
Run calcmean and verify that the correct message displays for the calculated overallMean. For example:
overallMean =
0.5178
Mean is greater than expected
Script Locations
MATLAB looks for scripts and other files in certain places. To run a script, the file must be in the current folder or in a folder on the search path.
By default, the MATLAB folder that the MATLAB Installer creates is on the search path. If you want to store and run programs in another folder, add it to the search path. Select the folder in the Current Folder browser, right-click, and then select Add to Path.
Help and Documentation
All MATLAB® functions have supporting documentation that includes examples and describes the function inputs, outputs, and calling syntax. There are several ways to access this information from the command line:
-
Open the function documentation in a separate window using the doc command.
doc mean （会打开文档帮助器）
