apply

Apply a function looping over a dimension of a matrix

This function should help when it is difficult to generalize a function to operate on all dimensions.

Examples
--------
Take the eig of each page in the 3rd dimension

b = apply(@eig,rand(4,4,3),3,'uni',0)

Normalize each column
b = apply(@norm, rand(5,3), 2)

Normalize each row
b = apply(@norm, rand(5,3), 1)
