    NAME
         claswp - perform a series of row interchanges on the  matrix
         A
    
    SYNOPSIS
         SUBROUTINE CLASWP( N, A, LDA, K1, K2, IPIV, INCX )
    
         INTEGER INCX, K1, K2, LDA, N
    
         INTEGER IPIV( * )
    
         COMPLEX A( LDA, * )
    
    
    
         #include <sunperf.h>
    
         void claswp(int n, complex *ca, int lda, int k1, int k2, int
                   *ipivot, int incx) ;
    
    PURPOSE
         CLASWP 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) COMPLEX 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  inter-
                   change will be done.
    
         K2        (input) INTEGER
                   The last element of IPIV for which  a  row  inter-
                   change 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  inter-
                   changed.
    
         INCX      (input) INTEGER
                   The increment between successive values  of  IPIV.
                   If  IPIV  is  negative,  the pivots are applied in
                   reverse order.
