A = arrayfun(fun, S)

[A, B, ...] = arrayfun(fun, S, ...)
[A, ...] = arrayfun(fun, S, ..., 'param1', value1, ...)
Description
A = arrayfun(fun, S) applies the function specified by fun to each element
 of array S, and returns the results in array A. 

The value A returned by arrayfun is the same size as S, and the 
(I,J,...)th element of A is equal to fun(S(I,J,...)). 

The first input argument fun is a function handle to a function that takes 
one input argument and returns a scalar value. fun must return values of 
the same class each time it is called.
