设置线条和窗口颜色
>> set(h1,'color',[1 0 0])%线条红色 >> set(gcf,'color','b')%背景蓝色
二、
clear x=0:2*pi/180:2*pi; y1=sin(x); y2=cos(x); plot(x,y1,x,y2,x,zeros(size(x)),'w');
h=get(gcf,'children');%得到图片属性 hh=get(gca,'children');%得到三条线的的属性
y11=get(hh(2),'ydata');%获取cos(x)的幅度，等于y2 set(hh(2),'ydata',y11/2);%设置新的幅度 set(hh(3),'linestyle','-.');%设置格式
set(gca,'DefaultTextColor',[1 0 0])%设置字体颜色
gtext('正弦')%添加字体，鼠标选择位置，点击出现
gtext('余弦')
set(0,'defaultfigurecolor',[0.9 0.9 0.9])%设置图片背景颜色
set(0,'defaultfigurecolor','default')%恢复为默认值
k=menu('请选择','plot','mesh','surf')
二、
1、把控件安装在图形窗口上
clear
h1=uicontrol('style','edit','tooltipstring','edit text')
h2=uicontrol('style','checkbox','position',[90 20 30 20],'tooltipstring','checkbox')
h3=uicontrol('style','listbox','position',[150 20 40 20],'tooltipstring','listbox')%[a b c d],(a,b)左下角位置，（c,d）宽和高
h4=uicontrol('style', 'pushbutton', 'Position' ,[210,20,30,20],'TooltipString', 'pushbutton')
h5=uicontrol('style', 'radiobutton', 'Position' ,[260,20,30,20],'TooltipString', 'Radiobutton')
2、
clear all
axes('position',[0.1 0.1 0.5 0.2])%坐标位置
x=0:0.5:10;y=x;plot(x,y)
axis([0 10 2 10])%显示范围
3、
clear all
subplot(2,1,1)
membrane %这是一个库函数
light('color',[0.9 0.5 0.1],'position',[0,-2,1])%风格省略为无穷远，光顺序通过(0 0 0)和(0 -2 1)
subplot(2,1,2)
membrane
light('color',[0.9 0.0 0.1],'style','local','position',[1,-1,1])%风格为本地光，光源在(1 -1 1)位置
4、
clear all
figure('color',[1 0.1 0],'position',[0 0 200 100],'name','ww')
三、imagesc
1、imagesc(A)将矩阵A中的元素数值按大小转化为不同颜色，并在坐标轴对应位置处以这种颜色染色。
clear all C = [0 2 4 6; 8 10 12 14; 16 18 20 22]; imagesc(C) colorbar
2、更改坐标轴
clear all x = [5 8]; y = [3 6]; C = [0 2 4 6; 8 10 12 14; 16 18 20 22]; imagesc(x,y,C) colorbar
翻转y轴
clear all x = [5 8]; y = [3 6]; C = [0 2 4 6; 8 10 12 14; 16 18 20 22]; imagesc(x,y,C) colorbar axis xy;
clear all x = [5 8]; y = [3 6]; C = [0 2 4 6; 8 10 12 14; 16 18 20 22]; imagesc(x,y,C) colorbar axis xy%翻转y轴 set(gca,'XDir','reverse')%翻转x轴
3、限制高度
C = [0 2 4 6; 8 10 12 14; 16 18 20 22]; clims = [4 18]; imagesc(C,clims) colorbar
4、更改显示色调
clear C = [1 2 3; 4 5 6; 7 8 9]; im = imagesc(C); im.AlphaData = .5;
5、投影面
clear Z = 10 + peaks; surf(Z) hold on imagesc(Z) colorbar
四、shading阴影函数
clear all
figure
subplot(2,2,1)
sphere(16)
title('Faceted Shading (Default)')
subplot(2,2,2)
sphere(16)
shading flat
title('Flat Shading')
subplot(2,2,3)
sphere(16)
shading interp
title('Interpolated Shading')
五、colorbar函数颜色
1、
close all; clear all; clc
figure(1)
surf(peaks(30))
colorbar('YTickLabel',{'Freezing','Cold','Cool','Neutral','Warm','Hot','Burning','Nuclear'})
2、
close all; clear all; clc
figure(1)
surf(peaks(30))
colormap jet
colorbar('YTickLabel',{'Freezing','Cold','Cool','Neutral','Warm','Hot','Burning','Nuclear'})
3、
close all; clear all; clc
figure(1)
surf(peaks(30))
colormap jet
colorbar('location','SouthOutside','YTickLabel',{'Freezing','Cold','Cool','Neutral','Warm','Hot','Burning','Nuclear'})
六、findobj
1、
close all;clear;clc;
plot(1:10)
xlabel xlab %x轴名称为“xlab”
disp('findobj返回的对象句柄')
h=findobj
h1=findobj('tag','figure')
