12 Programming Tips
For M-file functions, case requirements depend on the case sensitivity of the
operating system you are using. As a rule, naming and calling functions using
lowercase generally makes your M-files more portable from one operating
system to another.
Getting a Function’s Name and Path
To obtain the name of an M-file that is currently being executed, use the
following function in your M-file code.
mfilename
To include the path along with the M-file name, use
mfilename('fullpath')
For more information: See the mfilename function reference page.
WhatM-FilesDoesaFunctionUse?
For a simple display of all M-files referenced by a particular function, follow
the steps below:
1 Type clear functions to clear all functions from memory (see Note below).
2 Execute the function you want to check. Note that the function arguments
youchoosetouseinthisstepareimportant,sinceyoucangetdifferent
results when calling the same function with different arguments.
3 Type inmem to display all M-Files that were used when the function ran. If
you want to see what MEX-files were used as well, specify an additional
output, as shown here:
[mfiles, mexfiles] = inmem
Note clear functions does not clear functions locked by mlock. Ifyou
have locked functions, (which you can check using inmem), unlock them with
munlock, and then repeat step 1.
