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. !>
