The parallel toolbox has some tools that might help you. Find below some example pasted from the Matlab help
并行工具箱中有一些可能对您有所帮助的工具。在下面找到一些从 Matlab 帮助中粘贴的示例
matlabpool % Use default parallel configuration
spmd % By default uses all labs in the pool
INP = load(['somedatafile' num2str(labindex) '.mat']);
RES = somefun(INP);
end
Then the values of RESon the labs are accessible from the client as RES{1}from lab 1, RES{2}from lab 2, etc.
然后RES可以从客户端访问实验室上的值，如RES{1}实验室 1、RES{2}实验室 2 等。
You might also look at parforas a simple parallel replacement of for. Hope this helps even if it's not exactly what you're looking for.
您也可以将其parfor视为for. 希望这会有所帮助，即使它不是您正在寻找的内容。

I do not believe there is any built in multithreading support from MATLAB. This comes from both a conversation I had with a coworker recently and a quick google search
我不相信 MATLAB 有任何内置的多线程支持。这来自我最近与一位同事的一次谈话和一个快速的谷歌搜索
Hope this helps.
希望这可以帮助。

You may do it with MEX files and std::thread(see here).
您可以使用 MEX 文件和std::thread（请参阅此处）来执行此操作。
I have not tried to call mexEvalStringfrom the MEX file, and quite possibly it will result in a runtime error or freeze MATLAB for the time of execution. But if you can write that specific piece of code in C++, it may be what you're looking for.
我没有尝试mexEvalString从 MEX 文件中调用，很可能会导致运行时错误或在执行时冻结 MATLAB。但是，如果您可以用 C++ 编写那段特定的代码，那么它可能就是您要找的。
