How to put Matlab variables into dos command

Hello,

I'd like to launch a DOS command from Matlab (with dos('...')) the problem comes from DOS arguments which are Matlab variables. I've tried : dos('teuma.exe -b2a matlab_variable) but it obviously doesn't work. I've also tried to concanetate with brackets [] but without succes. Can someone help me?

Thank you very much

Do you want to pass the value in matlab_variable in the dos command? That is, if matlab_variable = 42, you're trying to issue the dos command "teuma.exe -b2a 42"? If so,

str = ['teuma.exe -b2a ',num2str(matlab_variable)];
dos(str)
