Function/Subroutine Documentation
subroutine zlaswp (integer N, complex*16, dimension( lda, * ) A, integer LDA, integer K1, integer K2, integer, dimension( * ) IPIV, integer INCX)ZLASWP performs a series of row interchanges on a general rectangular matrix. Purpose: ZLASWP 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*16 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.Author: Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd. Date: June 2017 Further Details: Modified by
