Functions/Subroutines


subroutine ZLAPMR (forwrd, m, n, x, ldx, k)
ZLAPMR rearranges rows of a matrix as specified by a permutation vector.

Function/Subroutine Documentation

subroutine ZLAPMR (logical forwrd, integer m, integer n, complex*16, dimension( ldx, * ) x, integer ldx, integer, dimension( * ) k)

ZLAPMR rearranges rows of a matrix as specified by a permutation vector.

Purpose:

!>
!> ZLAPMR 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*16 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.
