Returns a matrix of integers indicating the number of their slice in a
given array.

Usage

slice.index(x, MARGIN)

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.

See Also

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.
