Did you make sure that you added the directories for the SOM Toolbox to your MATLAB path?

You can use pathtool() to add them.

MATLAB: Undefined function ‘nmf’ for input arguments of type ‘double’

As Matt's comment correctly suggests, you have to add the folder (directory) where the function is located to the MATLAB path. If your function is in c:\mfiles for example, use

 >>addpath 'c:\mfiles'

or use the

 >>pathtool

to add the folder. The type error message is not saying the type is wrong, it's basically saying "you tried to call nmf() on a double input, but I don't know what nmf is".
