how to determine if another instance of matlab is running ?

8 views (last 30 days)
hi, anyone who can tell me how to determine if another instance of matlab is running? (using a 'trick' right now: automatically write a dummy file when starting up matlab and deleting it when closing. checking for this file tells me if matlab is running or not. but there has to be a more elegant way (that also works if matlab closes not the way it should) I reckon?) thanks!

A little more information about your OS, MATLAB version, and licensing, would be helpful.

Hi,
on windows you can do:
[out, res] = dos('tasklist')
This will give you a list of all running programs. Search in that list for matlab.exe:
strfind(res,'MATLAB.exe')
On Linux you can use the top command to get the list.

thanks Friedrich,
when matlab is running a second instance, matlab.exe is indeed twice in the task list. so this will do!
