##### Arguments
x

an array. If x has no dimension attribute, it is considered a one-dimensional array.

MARGIN

an integer giving the dimension number to slice by.

##### Value

An integer array y with dimensions corresponding to those of x such that all elements of slice number i with respect to dimension MARGIN have value i.

row and col for determining row and column indexes; in fact, these are special cases of slice.index corresponding to MARGIN equal to 1 and 2, respectively when x is a matrix.
