Run cmd command from MATLAB

Hi

I want to use a MATLAB command to run a command in windows cmd.

For example I need to run this command:

C:\Program Files\prism-4.5\bin>prism test.sm -mdp -noprobchecks -exporttrans poll2.tra

This is a command to use external software called Prism and the output of this command is the file "poll2.tra".

I tried to use this command:

system(['set PATH=' C:\Program Files\prism-4.5\bin>' && 'prism test.sm -mdp -noprobchecks -exporttrans poll2.tra])

but it does not work.

Problem is solved.

Now I use this command:

system('prism test.sm -mdp -noprobchecks -exporttrans poll2.tra')

and I moved test.sm file to the current folder of Matlab and it works now.

Although I prefered to use other folder path.

Anyway, its solved!

The system command can definitely be used for this purpose. I suspect that your problem is with the string you are passing the command. I would first verify directly in the command window that the command as written is correct. If that is ok, then I suspect the problem is with the included quotation marks. Please see this link from @Image Analyst for some help with that

You should not set the PATH, but you should use cd instead to change the directory inside your system call.

I personally prefer to write my code to a temporary bat file, which gives you some more flexibility in writing the code.
