You can use the built in function system(command) to execute the given command in windows cmd (It also works in Linux). You may use system('"file.exe" argument1 argument2') where the file path of "input.txt" can be entered in the arguments. You may find more information regarding system in the MATLAB documentation.

Program exe file and input.txt is in same working folder.
i wrote
filename = 'input.txt';
system('iri.exe', filename)

I remember using this command once or twice with the following command:
file = 'home/..../file.exe' %full path
val = [file, ' &']) %here, & pushes the command to the background
status = system(val fname)
This worked fine and I got no errors. You can skip the comma between .exe file and input file.
'Varargout' errors show up when the function does not have the proper output variable format.
You can go through following links for more details:
