# HPL_dlaswp01T man page

HPL_dlaswp01T — copies rows of A into itself and into U.

## Synopsis

**#include "hpl.h"****void HPL_dlaswp01T( const int** *M*, **const int** *N*, **double *** *A*, **const int** *LDA*, **double *** *U*, **const int** *LDU*, **const int *** *LINDXA*, **const int *** *LINDXAU* **);**

## Description

**HPL_dlaswp01T** copies scattered rows of A into itself and into an array U. The row offsets in A of the source rows are specified by LINDXA. The destination of those rows are specified by LINDXAU. A positive value of LINDXAU indicates that the array destination is U, and A otherwise. Rows of A are stored as columns in U.

## Arguments

- M (local input) const int
- On entry, M specifies the number of rows of A that should be moved within A or copied into U. M must be at least zero.
- N (local input) const int
- On entry, N specifies the length of rows of A that should be moved within A or copied into U. N must be at least zero.
- A (local input/output) double *
- On entry, A points to an array of dimension (LDA,N). The rows of this array specified by LINDXA should be moved within A or copied into U.
- LDA (local input) const int
- On entry, LDA specifies the leading dimension of the array A. LDA must be at least MAX(1,M).
- U (local input/output) double *
- On entry, U points to an array of dimension (LDU,M). The rows of A specified by LINDXA are copied within this array U at the positions indicated by positive values of LINDXAU. The rows of A are stored as columns in U.
- LDU (local input) const int
- On entry, LDU specifies the leading dimension of the array U. LDU must be at least MAX(1,N).
- LINDXA (local input) const int *
- On entry, LINDXA is an array of dimension M that contains the local row indexes of A that should be moved within A or or copied into U.
- LINDXAU (local input) const int *
- On entry, LINDXAU is an array of dimension M that contains the local row indexes of U where the rows of A should be copied at. This array also contains the local row offsets in A where some of the rows of A should be moved to. A positive value of LINDXAU[i] indicates that the row LINDXA[i] of A should be copied into U at the position LINDXAU[i]; otherwise the row LINDXA[i] of A should be moved at the position -LINDXAU[i] within A.
