Your string in the command

> When I am using the 'Execute' statement to run a matlab file from python, I use the statement on python:
>>>h.Execute ("run('H:\rishika\MATLAB\filewrite.m')")

uses unescaped backslashes, so \r is getting seen as Carriage Return
in the string being sent to Matlab. The \f will also be seen as a form
feed. I imagine that would confuse Matlab.

You should either double the backslashes

    >>>h.Execute ("run('H:\\rishika\\MATLAB\\filewrite.m')")

or use raw strings

    >>>h.Execute ("run(r'H:\rishika\MATLAB\filewrite.m')")
