HPL_dlaswp04N - Man Page
copy rows of U in A and replace them with columns of W.
Synopsis
#include "hpl.h"
void HPL_dlaswp04N( const int M0, const int M1, const int N, double * U, const int LDU, double * A, const int LDA, const double * W0, const double * W, const int LDW, const int * LINDXA, const int * LINDXAU );
Description
HPL_dlaswp04N copies M0 rows of U into A and replaces those rows of U with columns of W. In addition M1 - M0 columns of W are copied into rows of U.
Arguments
- M0 (local input) const int
On entry, M0 specifies the number of rows of U that should be copied into A and replaced by columns of W. M0 must be at least zero.
- M1 (local input) const int
On entry, M1 specifies the number of columns of W that should be copied into rows of U. M1 must be at least zero.
- N (local input) const int
On entry, N specifies the length of the rows of U that should be copied into A. N must be at least zero.
- U (local input/output) double *
On entry, U points to an array of dimension (LDU,N). This array contains the rows that are to be copied into A.
- LDU (local input) const int
On entry, LDU specifies the leading dimension of the array U. LDU must be at least MAX(1,M1).
- A (local output) double *
On entry, A points to an array of dimension (LDA,N). On exit, the rows of this array specified by LINDXA are replaced by rows of U indicated by LINDXAU.
- LDA (local input) const int
On entry, LDA specifies the leading dimension of the array A. LDA must be at least MAX(1,M0).
- W0 (local input) const double *
On entry, W0 is an array of size (M-1)*LDW+1, that contains the destination offset in U where the columns of W should be copied.
- W (local input) const double *
On entry, W is an array of size (LDW,M0+M1), that contains data to be copied into U. For i in [M0..M0+M1), the entries W(:,i) are copied into the row W0(i*LDW) of U.
- LDW (local input) const int
On entry, LDW specifies the leading dimension of the array W. LDW must be at least MAX(1,N+1).
- LINDXA (local input) const int *
On entry, LINDXA is an array of dimension M0 containing the local row indexes A into which rows of U are copied.
- LINDXAU (local input) const int *
On entry, LINDXAU is an array of dimension M0 that contains the local row indexes of U that should be copied into A and replaced by the columns of W.
