Matlab:是否可以创建信号处理程序(.m脚本) [英] Matlab: Is it possible to create signal handlers (.m scripts)

问题描述

我已经阅读了文档等内容，但是看不到任何明显的内容.我想有一个信号处理程序，可以拦截^C，^\或其他一些按键，这些按键可用于中断长时间运行的脚本(每个离散计算通常为< 1s)并允许其退出优雅地保存当前状态.

I've looked through the documentation, etc, but I'm not seeing anything obvious. I'd like to have a signal handler that can intercept ^C, ^\, or some other keypress that could be used to interrupt a long-running script (each discrete computation is typically <1s) and allow it to exit gracefully and save current state.

Matlab确实具有COM的事件处理程序，但它仅适用于Windows，并且我处于* nix环境中.

Matlab does have event handlers for COM, but it's windows-only and I'm in a *nix environment.

如果答案是不走运"，我对此很满意……我只是没有看到任何表明我是SOL的东西.

If the answer is 'tough luck', I'm cool with that ... I'm just not seeing anything that says I'm SOL yet.

推荐答案

MATLAB已经将^C解释为中断.您可以使用onCleanup对象来确保正确保留程序状态. IE.像这样:

MATLAB already interprets ^C as an interrupt. You can use onCleanup objects to ensure that your program state is preserved correctly. I.e. something like:

function testFcn
x = onCleanup( @() disp('perform cleanup here...') );
for ii=1:1000, disp(ii), pause(1), end

执行上述操作，无聊时打^C.显然，您可以将任何函数句柄连接到onCleanup对象.另请参见 onCleanup的参考页.

Run the above and hit ^C when you get bored. Obviously, you can hook any function handle in to your onCleanup object. See also the reference page for onCleanup.
