NAME
       SRC/zlapmt.f

SYNOPSIS
   Functions/Subroutines
       subroutine zlapmt (forwrd, m, n, x, ldx, k)
           ZLAPMT performs a forward or backward permutation of the columns of
           a matrix.

Function/Subroutine Documentation
   subroutine zlapmt (logical forwrd, integer m, integer n, complex*16,
       dimension( ldx, * ) x, integer ldx, integer, dimension( * ) k)
       ZLAPMT performs a forward or backward permutation of the columns of a
       matrix.

       Purpose:


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