HPL_dlaswp00N — performs a series of row interchanges.

Synopsis

#include "hpl.h"
 void HPL_dlaswp00N( const int M, const int N, double * A, const int LDA, const int * IPIV );

Description

HPL_dlaswp00N performs a series of local row interchanges on a matrix A. One row interchange is initiated for rows 0 through M-1 of A.

Arguments

M       (local input)           const int

On entry, M specifies the number of rows of the array A to be interchanged. M must be at least zero.

N       (local input)           const int

On entry, N  specifies  the number of columns of the array A. N must be at least zero.

A       (local input/output)    double *

On entry, A  points to an array of dimension (LDA,N) to which the row interchanges will be  applied.  On exit, the permuted matrix.

LDA     (local input)           const int

On entry, LDA specifies the leading dimension of the array A. LDA must be at least MAX(1,M).

IPIV    (local input)           const int *

On entry,  IPIV  is  an  array of size  M  that  contains the pivoting  information.  For  k  in [0..M),  IPIV[k]=IROFF + l implies that local rows k and l are to be interchanged.
