NAME
       SRC/dlaswp.f

SYNOPSIS
   Functions/Subroutines
       subroutine dlaswp (n, a, lda, k1, k2, ipiv, incx)
           DLASWP performs a series of row interchanges on a general
           rectangular matrix.

Function/Subroutine Documentation
   subroutine dlaswp (integer n, double precision, dimension( lda, * ) a,
       integer lda, integer k1, integer k2, integer, dimension( * ) ipiv,
       integer incx)
       DLASWP performs a series of row interchanges on a general rectangular
       matrix.

       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.

       Parameters
           N

                     N is INTEGER
                     The number of columns of the matrix A.

           A

                     A is 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

                     LDA is INTEGER
                     The leading dimension of the array A.

           K1

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

           K2

                     K2 is INTEGER
                     (K2-K1+1) is the number of elements of IPIV for which a row
                     interchange will be done.

           IPIV

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

           INCX

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