File name of currently running code


p = mfilename('fullpath')
c = mfilename('class')


mfilename returns a character vector containing the file name of the file in which the function call occurs. When called from within the file, it returns the name of that file. This allows a script or function to determine its name.

p = mfilename('fullpath') returns the full path and name of the file in which the call occurs, not including the filename extension.

c = mfilename('class') in a method, returns the class of the method, not including the leading @ sign. If called from a nonmethod, it yields the empty character vector.


If mfilename is called with any argument other than the above two, it behaves as if it were called with no argument.

When called from the command line, mfilename returns an empty character vector.

To get the names of the callers of a MATLAB® function file, use dbstack with an output argument.
