NAME

       LAPACK-3 - performs 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 (K2*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.
