如何在命令行脚本完成之后停止返回MATLAB？ [英] How can I stop MATLAB from returning until after a command-line script completes?

问题描述

我在MATLAB帮助（ matlab -h ）中看到，我可以使用 -r m - 要运行的文件。我注意到当我这样做，MATLAB似乎启动脚本，但立即返回。脚本处理正常，但主应用程序已经返回。

I see in the MATLAB help (matlab -h) that I can use the -r flag to specify an m-file to run. I notice when I do this, MATLAB seems to start the script, but immediately return. The script processes fine, but the main app has already returned.

有什么办法让MATLAB只在命令完成后返回？如果你从一个单独的程序调用它，似乎比等待使用一个文件或套接字来确认完成更容易等待。

Is there any way to get MATLAB to only return once the command is finished? If you're calling it from a separate program it seems like it's easier to wait on the process than to use a file or sockets to confirm completion.

为了说明，这里示例函数 waitHello.m ：

To illustrate, here's a sample function waitHello.m:

function waitHello
    disp('Waiting...');
    pause(3); %pauses 3 seconds
    disp('Hello World');
    quit;

我试着运行：

matlab -nosplash -nodesktop -r waitHello

推荐答案

快速回答：

matlab -wait -nosplash -nodesktop -r waitHello

在Matlab 7.1（版本我有）在matlab.bat有一个未记录的命令行选项-wait。如果它不适合你的版本，你可以添加它。这是我发现的。最后启动matlab的命令是（行153）：

In Matlab 7.1 (the version I have) there is an undocumented command line option -wait in matlab.bat. If it doesn't work for your version, you could probably add it in. Here's what I found. The command at the bottom that finally launches matlab is (line 153):

start "MATLAB" %START_WAIT% "%MATLAB_BIN_DIR%\%MATLAB_ARCH%\matlab" %MATLAB_ARGS%

start命令的相关语法help start在cmd.exe中）在这种情况下是：

The relevant syntax of the start command (see "help start" in cmd.exe) in this case is:

start ["window title"] [/wait] myprogram.exe args ...

在所有记录的命令行选项中， （line 60）：

A bit higher, among all of the documented command line options, I found (line 60):

) else if (%opt%) == (-wait) (
  set START_WAIT=/wait
) else (

所以指定-wait应该做什么，只要你也从你的脚本退出matlab（否则它会等待你以交互方式终止）。

So specifying -wait should do what you want, as long as you're also exiting matlab from your script (otherwise it will wait for you to terminate it interactively).
