ZLASWP(l) ) ZLASWP(l)
ZLASWP - perform a series of row interchanges on the matrix A
SUBROUTINE ZLASWP( N, A, LDA, K1, K2, IPIV, INCX )
INTEGER INCX, K1, K2, LDA, N
INTEGER IPIV( * )
COMPLEX*16 A( LDA, * )
ZLASWP performs a series of row interchanges on the matrix A. One row interchange is ini-
tiated for each of rows K1 through K2 of A.
N (input) INTEGER
The number of columns of the matrix A.
A (input/output) 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 (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 (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 interchanged.
INCX (input) INTEGER
The increment between successive values of IPIV. If IPIV is negative, the pivots
are applied in reverse order.
