How to call STAAD.exe in Matlab

Hi,

I usually use this command to run STAAD models. I use it in a loop, so in each loop std.std is a different model. That's handy.

dos('C:\SProV8i\STAAD\SProStaad\SProStaad.exe /s std.std');

But with the STAAD Pro Connect Edition, the command doesn't work anymore.

I have updated the .exe folder location, and STAAD is opened. but the model is not run.  

Thanks in advance.

regards, Huijun
