NAME
       DLAPMT - rearrange 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

SYNOPSIS
       SUBROUTINE DLAPMT( FORWRD, M, N, X, LDX, K )

	   LOGICAL	  FORWRD

	   INTEGER	  LDX, M, N

	   INTEGER	  K( * )

	   DOUBLE	  PRECISION X( LDX, * )

PURPOSE
       DLAPMT  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.

ARGUMENTS
       FORWRD  (input) LOGICAL
	       = .TRUE., forward permutation = .FALSE., backward permutation

       M       (input) INTEGER
	       The number of rows of the matrix X. M >= 0.

       N       (input) INTEGER
	       The number of columns of the matrix X. N >= 0.

       X       (input/output) DOUBLE PRECISION array, dimension (LDX,N)
	       On entry, the M by N matrix X.  On exit, X contains the permuted matrix X.

       LDX     (input) INTEGER
	       The leading dimension of the array X, LDX >= MAX(1,M).

       K       (input) INTEGER array, dimension (N)
	       On entry, K contains the permutation vector.
