Let Matlab continue without waiting for a result

Question

I have the following question: How do I tell Matlab that it should not wait for the results of a function? Is there a way other than threads?

My problem: I have a fu

Answer 1

In your function B, just call the batch file with a & at the end of the line.

For example:

!mybatch.bat &

This will run the file mybatch.bat in background mode and will return execution to Matlab immediately after the call.

or if you prefer the complete form:

[status, result] = system('mybatch.bat &')

But in this case it is a bit useless, since the system call mybatch in the background, the result variable is always empty and status is always 0 (whether a file mybatch.bat was found and executed or not)

edit: That is the quick trick in case it is only the batch file execution which is slowing down your program.

If you have more matlab instructions in function B and you really need function A to go on without waiting, you will have to set up a listener object with function B as a callback. Then in your function A, trigger the event (which will activate the listener and call function B).
