In GNU Octave version 3.4.3, I am having trouble applying a custom function to operate on each item/element in a matrix.

I have a (2,3) matrix that looks like:

mymatrix = [1,2,3;4,5,6];

mymatrix

   1   2   3
   4   5   6

I want to use each element of the matrix as an input, and run a custom function against it, and have the output of the function replace the content of mymatrix item by item.
