从 C 调用 MATLAB
使用
mxArray 从 C 程序中运行 MATLAB® 代码引擎应用程序是程序，它们允许您从自己的 C/C++ 程序调用 MATLAB，从而将 MATLAB 用作计算引擎。要编译 C 引擎应用程序，请调用 mex 函数。
注意
推荐使用 MATLAB Engine API for C++ 而不是 Engine API for C。MATLAB Engine API for C++ 包含用于编写引擎应用程序的现代 C++ 功能。有关详细信息，请参阅从 C++ 调用 MATLAB。目前没有删除 Engine API for C 的计划。
引擎应用程序需要已安装版本的 MATLAB；您无法在只有 MATLAB Runtime 的机器上运行 MATLAB Engine。
要编译 C Engine 应用程序，您需要：
编写 C 源代码的经验。您可以使用 Engine API for C 和 C Matrix API 函数创建 C 源代码文件。
MATLAB 支持的编译器。有关支持的编译器的最新列表，请参阅支持和兼容的编译器。
使用具有
-client engine选项的mex编译脚本。
Engine API for C
Engine | MATLAB 引擎的类型 |
engOpen | Start MATLAB engine session |
engOpenSingleUse | Start MATLAB engine session for single, nonshared use |
engClose | Quit MATLAB engine session |
engEvalString | Evaluate expression in string |
engGetVariable | Copy variable from MATLAB engine workspace |
engPutVariable | Put variable into MATLAB engine workspace |
engGetVisible | Determine visibility of MATLAB engine session |
engSetVisible | Show or hide MATLAB engine session |
engOutputBuffer | Specify buffer for MATLAB output |
