PURPOSE
  CLAPMT - 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

SYNTAX
  SUBROUTINE CLAPMT( FORWRD, M, N, X, LDX, K )

      LOGICAL	     FORWRD

      INTEGER	     LDX, M, N

      INTEGER	     K( * )

      COMPLEX	     X( LDX, * )

DESCRIPTION
  CLAPMT 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) COMPLEX 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.
