I am trying to get the file name of the lastly invoked mfile using the following command.
a=mfilename('fullpath')
but workspace is returning null. http://i46.tinypic.com/309hk4o.jpg

I'm working on MATLAB Version 7.13.0.564 (R2011b)

The documentation says: "When called from the command line, mfilename returns an empty string."

@Sudharsan: This means, that your expectations are the mistake. What do you want to obtain in the command line?

mfilename only works inside the script when it's running. I don't know that that information on the last m-file that was run is kept, or if it is, if it's available for you to easily get. Maybe it's kept somewhere, though I don't know where. You might try poking around http://undocumentedmatlab.com/

Might be able to get it from the command history:
