Pass parameters to a .exe file and run it.

Hello everyone,
I have a .exe file (which is saved locally) compiled using Visual Studio C#. Now I am writing a software, one of the functions I need is to pass some parameters I got in MATLAB, call and pass these parameters to the .exe file, run .exe file, and save the output locally.
Could anyone please tell how could I do this? Specifically, I am facing the difficulties that I don't know how to use MATLAB to pass parameters to the .exe file and call it to run.
Thank you very much in advance.

The function whose name will become the name of the executable: declare it with (varargin) instead of with no parameters.
When you invoke the executable, pass the parameters you want on the command line that invokes the executable. (You might have to frame this differently for C#)
Inside of the main function, you can examine nargin() to find out how many parameters were passed, and you can access them as varargin{1}, varargin{2}, and so on.
Now the important part: each parameter will be received as a string, so if it is intended to represent a number, convert the string to a number before using the value. But avoid using str2num() for doing that, please, as that exposes security holes.
