Hi,
I tried this method and tried to pass two variables with string values.

system('fitD.exe',sprintf('%s',imagePath),sprintf('%s',FileName));

But I get an error message saying Too many input arguments.
How can I solve this problem?
Thanks

Hi Kalani,

Are imagePath and FileName two different variable in which value of the string is stored? if not try passing without using sprintf i.e. system('fitD.exe', 'imagePath' ,'FileName');

No, that will not work. system() only permits a single parameter, and
you are suggesting to pass it three parameters.

Yes. you are correct, system function can returns two parameters [status, result] after executing the system command, but only accepts one parameter, that is why you get the error "too many input arguments".

I got it to work by writing as system(['fitD.exe ' imagePath ' ' FileName]) Thanks all.
