`mfilename`

Returns the name of the file that is running.

Syntax

name = mfilename

Returns the file name without path or extension.

p = mfilename('fullpath')

Returns the path including the file name, without the extension.

d = mfilename('fullpathext')

Returns the path including name and extension.

Description

Inside a function file, mfilename is the name of that file, which lets error messages or log lines name their origin without hard-coding it. Called from a script, it gives the script's name. When there is no file, as in code typed at the prompt, the result is empty.

Input arguments

'fullpath': Option that adds the folder to the result.
'fullpathext': Option that adds the folder and the extension.

Output arguments

name: Character vector; empty when called from the command line or from code with no file.

Example

A function reporting its own file name

writelines(["function r = who_am_i()", "  r = mfilename;", "end"], 'who_am_i.m');
who_am_i

Output

ans = 'who_am_i'

mfilename
