在qt界面中调用matlab engine并嵌入Matlab cmd Window

本文详细介绍如何在QT环境下调用MATLAB引擎，包括配置步骤、线程操作、窗口嵌入及Windows API调用等关键操作。通过实例代码，展示了从创建项目到实现MATLAB功能的全过程。

环境：win10+QT(编译器：MSVC 2017 64-bit)+Matlab 2016a 64-bit

在这里插入图片描述

主体思路如下（参考：https://blog.youkuaiyun.com/humanking7/article/details/86040954，做了些简化）

主要操作

涉及到的操作主要有：

qt下启动线程操作；
qt下调用matlab engine 的配置；
qt嵌入外部程序的窗口；
qt调用windows api；
