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 LIMITS none LINK LIBRARY none SEE ALSO join, sort ## Copyright (C) 1999 Landon Curt Noll ## ## Calc is open software; you can redistribute it and/or modify it under ## the terms of the version 2.1 of the GNU Lesser General Public License ## as published by the Free Software Foundation. ## ## Calc is distributed in the hope that it will be useful, but WITHOUT ## ANY WARRANTY; without even the implied warranty of MERCHANTABILITY ## or FITNESS FOR A PARTICULAR PURPOSE.
