NAME
reverse - reverse a copy of a list or matrix
SYNOPSIS
reverse(x)
TYPES
x list or matrix
return same type as x
DESCRIPTION
For a list or matrix x, reverse(x) returns a list or matrix in
which the order of the elements has been reversed. The original
list or matrix x is unchanged.
In the case of matrix x, the returned value is a matrix with
the same dimension and index limits, but the reversing is performed
as if the matrix were a linear array.
EXAMPLE
; A = list(1, 7, 2, 4, 2)
; print reverse(A)
list (5 elements, 5 nonzero):
[[0]] = 2
[[1]] = 4
[[2]] = 2
[[3]] = 7
[[4]] = 1
; mat B[2,3] = {1,2,3,4,5,6}
; print reverse(B)
mat [2,3] (6 elements, 6 nonzero):
[0,0] = 6
[0,1] = 5
[0,2] = 4
[1,0] = 3
[1,1] = 2
[1,2] = 1
