dlapmt.f-SYNOPSIS

Functions/Subroutines subroutine dlapmt (FORWRD, M, N, X, LDX, K) DLAPMT performs a forward or backward permutation of the columns of a matrix.Function/Subroutine Documentation subroutine dlapmt (logicalFORWRD, integerM, integerN, double precision, dimension( ldx, * )X, integerLDX, integer, dimension( * )K) DLAPMT performs a forward or backward permutation of the columns of a matrix. Purpose: DLAPMT rearranges the columns of the M by N matrix X as specified by the permutation K(1),K(2),...,K(N) of the integers 1,...,N. If FORWRD = .TRUE., forward permutation: X(*,K(J)) is moved X(*,J) for J = 1,2,...,N. If FORWRD = .FALSE., backward permutation: X(*,J) is moved to X(*,K(J)) for J = 1,2,...,N. Parameters: FORWRD FORWRD is LOGICAL = .TRUE., forward permutation = .FALSE., backward permutation M M is INTEGER The number of rows of the matrix X. M >= 0. N N is INTEGER The number of columns of the matrix X. N >= 0. X X is DOUBLE PRECISION array, dimension (LDX,N) On entry, the M by N matrix X. On exit, X contains the permuted matrix X. LDX LDX is INTEGER The leading dimension of the array X, LDX >= MAX(1,M). K K is INTEGER array, dimension (N) On entry, K contains the permutation vector. K is used as internal workspace, but reset to its original value on output. Author: Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd.
