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.

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.

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).
—DIV
