       dlapmt.f -

SYNOPSIS

   Functions/Subroutines
       subroutine dlapmt (FORWRD, M, N, X, LDX, K)
	   DLAPMT performs a forward or backward permutation of the columns of a matrix.

Function/Subroutine Documentation
   subroutine dlapmt (logicalFORWRD, integerM, integerN, double precision, dimension( ldx, * )X, integerLDX, integer, dimension( * )K)
       DLAPMT performs a forward or backward permutation of the columns of a matrix.

       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.

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