.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)".

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。
