DLASWP(l)			       )			     DLASWP(l)

NAME
       DLASWP - perform a series of row interchanges on the matrix A

SYNOPSIS
       SUBROUTINE DLASWP( N, A, LDA, K1, K2, IPIV, INCX )

	   INTEGER	  INCX, K1, K2, LDA, N

	   INTEGER	  IPIV( * )

	   DOUBLE	  PRECISION A( LDA, * )

PURPOSE
       DLASWP  performs	 a series of row interchanges on the matrix A. One row
       interchange is initiated for each of rows K1 through K2 of A.

ARGUMENTS
       N       (input) INTEGER
	       The number of columns of the matrix A.

       A       (input/output) DOUBLE PRECISION array, dimension (LDA,N)
	       On entry, the matrix of column dimension N  to  which  the  row
	       interchanges will be applied.  On exit, the permuted matrix.

       LDA     (input) INTEGER
	       The leading dimension of the array A.

       K1      (input) INTEGER
	       The  first  element of IPIV for which a row interchange will be
	       done.

       K2      (input) INTEGER
	       The last element of IPIV for which a row	 interchange  will  be
	       done.

       IPIV    (input) INTEGER array, dimension (M*abs(INCX))
	       The vector of pivot indices.  Only the elements in positions K1
	       through K2 of IPIV are accessed.	 IPIV(K) = L  implies  rows  K
	       and L are to be interchanged.

       INCX    (input) INTEGER
	       The  increment  between	successive values of IPIV.  If IPIV is
	       negative, the pivots are applied in reverse order.
