claswp.f -

SYNOPSIS
Functions/Subroutines
subroutine claswp (N, A, LDA, K1, K2, IPIV, INCX)
CLASWP performs a series of row interchanges on a general
rectangular matrix.

Function/Subroutine Documentation
subroutine claswp (integerN, complex, dimension( lda, * )A, integerLDA,
integerK1, integerK2, integer, dimension( * )IPIV, integerINCX)
CLASWP performs a series of row interchanges on a general rectangular
matrix.

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.

Parameters:
N

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

A

A is 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

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
The last element of IPIV for which a row interchange will
be done.

IPIV

IPIV is 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

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