!> DLAPMR rearranges the rows of the M by N matrix X as specified

!> 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.

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 (M)
!>          On entry, K contains the permutation vector. K is used as
!>          internal workspace, but reset to its original value on
!>          output.
