lapmr(3) Library Functions Manual lapmr(3) NAME lapmr - lapmr: permute rows SYNOPSIS Functions subroutine clapmr (forwrd, m, n, x, ldx, k) CLAPMR rearranges rows of a matrix as specified by a permutation vector. subroutine dlapmr (forwrd, m, n, x, ldx, k) DLAPMR rearranges rows of a matrix as specified by a permutation vector. subroutine slapmr (forwrd, m, n, x, ldx, k) SLAPMR rearranges rows of a matrix as specified by a permutation vector. subroutine zlapmr (forwrd, m, n, x, ldx, k) ZLAPMR rearranges rows of a matrix as specified by a permutation vector. Detailed Description Function Documentation subroutine clapmr (logical forwrd, integer m, integer n, complex, dimension( ldx, * ) x, integer ldx, integer, dimension( * ) k) CLAPMR rearranges rows of a matrix as specified by a permutation vector. Purpose: CLAPMR rearranges the rows of the M by N matrix X as specified by the permutation K(1),K(2),...,K(M) of the integers 1,...,M. If FORWRD = .TRUE., forward permutation: X(K(I),*) is moved X(I,*) for I = 1,2,...,M. If FORWRD = .FALSE., backward permutation: X(I,*) is moved to X(K(I),*) for I = 1,2,...,M. 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 COMPLEX 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 (M) 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.
