function name

Why is it that a function does not work with some names? e.g. I named one of my functions magnuson(PathName) and the function would not work, it would return an error saying:

Undefined function 'magnuson' for input arguments of type 'char'.

Then after changing the name of the function to magnuson_LA(PathName) it worked perfectly. Why is this?

Usually that error comes when the function has been saved on path that MATLAB cannot reach.

Matlab checks for functions in the current directory and a saved list of paths.

To add a path to the search:

addpath('C:\...\')
