Issue with nume1 in MATLAB

Question

Here's a copy-paste of what MATLAB is doing after I type nume1(A) into the command window:

nume1(A)
%Undefined function 'nume1' for input arguments of type 'double'.

Did you mean:
numel(A)

ans =

 1034289

Does anyone know how to stop matlab from doing this? This is preventing me from using nume1 in the editor...

Answer 1

Let's assume this isn't a typo and you didn't mean to invoke the numel function.

Make sure you're not trying to call an M-script as a function. The first line in your nume1.m file should read something like

function argout = nume1(argin)

You should make sure your function is either on your MATLAB search path (type path in the Command Window to see what MATLAB's current search path is), or in your current working directory (type pwd). To see which function or script MATLAB will use, if any, type:

>> which nume1 -all

The top most is the one that will be invoked.
