Some folks might think: “you still use RCS”?!? And we will say, hey, at least we switched from SCCS to RCS back in … I think it was around 1994 ... at least we are keeping up! :-) :-) :-) Logs say that SCCS version 18 became RCS version 19 on 1994 March 18. RCS served us well. But now it is time to move on. And so we are switching to git. Calc releases produce a lot of file changes. In the 125 releases of calc since 1996, when I started managing calc releases, there have been 15473 file mods!

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
