Problem 375. N-Dimensional Array Slice
Given an N-dimensional array, A, an index, I, and a dimension, d, return the I th elements of A in the d dimension.
For Example,
array_slice( A, 5, 3 )
is equivalent to
A(:,:,5)
Note: eval and str2func cannot be used. This is a Cody restriction.

What test 3 means???
The question is simple yet really well thought. One of my very fundamental concepts got clarified after solving this problem.
Please, edit the problem to make it clear 'eval' cannot be used.
I think same like Fulaninho de Tal, You need edit the problem and it clear 'eval' and 'str2func' cannot be used.
How do do want to handle when the index is bigger than the size of the array? In solution 2 or 3 you enter a 5x5 array, but request slice index 10.
i like it
Massimo Zanetti & Kevin Hellemans: in Test 3 the value 10 is entered as the dimension argument (not the index argument, which has a value of 1).
Thus in Test 3 the general solution would be A(:, :, :, :, :, :, :, :, :, 1).
