I have both 32bit and 64bit versions of Matlab on my computer and I'd like to open only the 32 bit version via a batch file. But when I give the command 'start matlab', it opens the 64 bit version by default. Is there any way I can have it open the 32bit version ?

P.S - I don't know if it makes a difference, but my computer is 64bit.

在 MATLAB Online 中打开

What happens if you just put the full name of the executable in your batch file:

C:\Program Files (x86)\MATLAB\R2015a\bin\matlab.exe

I'm just worried it won't be robust. This batch file is going to be used on other computers and I'm not sure the editions will be the same..Is there any other way ?

You would need to have your batch file search for the proper directory.

You might be able to retrieve the registry entry for MATLAB and examine it to see what the pathname is. Or there might possibly be a more direct registry path.

The version of MATLAB that will be launched if you ask for matlab without a path is determined by the registry. See the -regserver option of MATLAB to register an executable as the default.
