SLASWP(3F)							    SLASWP(3F)


NAME    [Toc]    [Back]

     SLASWP - perform a	series of row interchanges on the matrix A

SYNOPSIS    [Toc]    [Back]

     SUBROUTINE	SLASWP(	N, A, LDA, K1, K2, IPIV, INCX )

	 INTEGER	INCX, K1, K2, LDA, N

	 INTEGER	IPIV( *	)

	 REAL		A( LDA,	* )

PURPOSE    [Toc]    [Back]

     SLASWP 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    [Toc]    [Back]

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

     A	     (input/output) REAL 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.
