Thread Subject:

preventing multiple instances of matlab

I give up with this one! When double-clicking on a fig file, a new instance of matlab starts, even though matlab is already running, and the fig file doesn't open. This is not very useful. Anyone know how to prevent this?
Thanks

I thought this has been the old behavior. since 2007x ML will open the file
using the existing ML session. What version of ML you have?

Hi Gouliang,

Thanks for your response. This was using R2008a. I might try a reinstall & see if it solves it.

Thanks,

Kevin

You don't need to resintall Matlab. This command http://www.mathworks.com/help/techdoc/matlab_env/rmvd_matlablink__14.html will associate .m files so that a new Matlab instance is not created.

Type the following in MATLAB help: "Utilities to Set Up File Associations on Windows Platforms". some links will be provided under this heading. click appropriate link.*.fig file will open and without multiple instances of MATLAB opening

I followed the instructions in the following link :http://www.mathworks.com/support/solutions/en/data/1-D9IA82/?solution=1-D9IA82 but still I had the multiple instances running when I was clicking on an m file at different directories in windows 7. However, I used another trick that worked fine:
Go to matlalbroot directory (your matlab installation folder), then go to toolbox\local folder. There, you'll find an m file named "pathdef.m". Right click on the file and from the properties go to the security tab. Click on "edit" and then "add" and add a user as "Everyone". Click ok and then apply. Restart matlab and the problem is gone.
This solved the problem for me.
