Multi-threading in MATLAB
提问by Maddy
I have read MATLAB's info on multi-threading and how it is in-built in certain functions. However, my requirement is different. Say, I have 3 functions: fun1(data1), fun2(data2), fun3(data3).... Can I implement multi-threading between these functions? I actually have 300+ functions using a lot of data. Multi-threading may help me cut down a lot of the time. Please suggest a command or something which I can further research on. Thanks!
我已经阅读了 MATLAB 关于多线程的信息以及它是如何内置在某些函数中的。但是，我的要求不同。比如说，我有 3 个函数：fun1(data1)、fun2(data2)、fun3(data3)……我可以在这些函数之间实现多线程吗？我实际上有 300 多个使用大量数据的函数。多线程可以帮助我减少很多时间。请建议一个命令或我可以进一步研究的东西。谢谢！

If you want to run a batch of different functions on different processors, you can use the Parallel Computing Toolbox, more specifically, a parforloop, but you need to pass the functions as a list of handles.
如果你想在不同的处理器上运行一批不同的函数，你可以使用 Parallel Computing Toolbox，更具体地说，是一个parfor循环，但你需要将函数作为句柄列表传递。
funList = {@fun1,@fun2,@fun3};
dataList = {data1,data2,data3}; %# or pass file names
matlabpool open
parfor i=1:length(funList)
%# call the function
funList{i}(dataList{i});
end
Edit:Starting with R2015a matlabpoolfunction has been removedfrom Matlab, you need to call parpoolinstead.
编辑：从 R2015a 开始matlabpool函数已从 Matlab 中删除，您需要改为调用parpool。

Try looking at the Parallel Computing Toolbox.(I'm unfortunately not too familiar with it, but that seems to be the right place.) Look at gatherand parallel for-loops.
尝试查看并行计算工具箱。（不幸的是，我对它不太熟悉，但这似乎是正确的地方。）查看gather并并行 for-loops。
