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
