从MATLAB调用C ++代码？ [英] Call C++ code from MATLAB?

问题描述

我有一些代码，我需要在C ++中编写代码，因为很大程度上依赖于模板。我想从MATLAB调用这个代码：基本上，我需要传递一些参数到C ++代码，并让C ++代码返回一个矩阵到MATLAB。我听说这是可能的东西叫做一个 MEX 文件，我仍在研究。但是我不知道这些MEX文件支持什么。是所有C ++（例如 STL 和 Boost ）？它是多么困难？

I have some code which I need to code in C++ due to heavy reliance on templates. I want to call this code from MATLAB: basically, I need to pass some parameters to the C++ code, and have the C++ code return a matrix to MATLAB. I have heard this is possible with something called a MEX file which I am still looking into. However I am not sure what is supported in these MEX files. Is all of C++ (e.g. STL and Boost) supported? How difficult is it?

编辑：我不需要任何共享库，只是头文件的东西，如 shared_ptr 。

I don't need any shared libraries, just header-only stuff like shared_ptr.

推荐答案

请查看 MEX文件指南，特别是关于C ++的第25-27节​​。
基本的 STL / Boost 数据结构应该可以正常工作，但使用Boost的线程可能会有问题。

cout 将无法按照预期在C ++中工作， mexPrintf 必须使用。

Have a look at the MEX-files Guide, especially Section 25–27 for C++. The basic STL/Boost data structures should work, but threading with Boost could be a problem.
cout will not work as expected in C++, mexPrintf has to be used instead.
