Function/Subroutine Documentation
subroutine dlaswp (integerN, double precision, dimension( lda, * )A, integerLDA, integerK1, integerK2, integer, dimension( * )IPIV, integerINCX)
DLASWP performs a series of row interchanges on a general rectangular matrix.
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.
Parameters:

N
N is INTEGER The number of columns of the matrix A.
AA is 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.
LDALDA is INTEGER The leading dimension of the array A.
K1K1 is INTEGER The first element of IPIV for which a row interchange will be done.
K2K2 is INTEGER The last element of IPIV for which a row interchange will be done.
IPIVIPIV 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.
INCXINCX is INTEGER The increment between successive values of IPIV. If IPIV is negative, the pivots are applied in reverse order.
