Friends,
I have this code which works fine:
system(['C:/My_program/folder_images/myexecutable.exe <' fname_path]);
But I need to use which() to determine where 'myexecutable.exe' is. So I'm trying to use this:
exe_path = which ('myexecutable.exe')
system(['exe_path <' fname_path]);
but it doesn't work. Can anybody help me please? Thank you in advance.

My advice is to first just display the string, without putting it into the system() command, to see if it is correct. I think you probably want
system_command_string = [exe_path,' < ',fname_path]
because both exe_path and fname_path are already strings, and you just need to put the ' < ' in between. (But you should check that.) Then,
system(system_command_string)
should run it.

which is a Matlab function, not a system command
Use dir() recursively instead.
