.net制作调用matlab画曲线软件的实现

此为制作效果图.

目标：输入几个点的值，根据这几个点，画出点的封闭的热力学曲线图。

实现思路：1将matlab与制作的程序放到一起进行发布：缺点：安装包较大。

             2或者使用.net模拟作图

第1种：代码：m文件代码：还需要一个figure文件

function varargout = untitled(varargin)
% UNTITLED MATLAB code for untitled.fig
%      UNTITLED, by itself, creates a new UNTITLED or raises the existing
%      singleton*.
%
%      H = UNTITLED returns the handle to a new UNTITLED or the handle to
%      the existing singleton*.
%
%      UNTITLED('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in UNTITLED.M with the given input arguments.
%
%      UNTITLED('Property','Value',...) creates a new UNTITLED or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before untitled_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to untitled_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
%
% See also: GUIDE, GUIDATA, GUIHANDLES

第二种代码：C#写的，如有需求，请直接给我发邮件，邮件地址在页面footer部分。具体思路是两点之间画9999个点，这9999个点每一点x,y均符合某一热力学公式，使其成为封闭曲线。

这两种方法均做了打包，如果对安装包大小不介意，那就可以直接用matlab，代码简单。如果觉得安装包比较大，那就直接用C#模拟吧。
