NAME

6       HPL_dlaswp01N - copies rows of A into itself and into U.

SYNOPSIS

9       #include "hpl.h"
10
11       void  HPL_dlaswp01N(  const  int  M, const int N, double * A, const int
12       LDA, double * U, const int LDU, const int * LINDXA, const int * LINDXAU
13       );

DESCRIPTION

16       HPL_dlaswp01N  copies   scattered rows  of  A  into itself  and into an
17       array  U.  The row offsets in  A  of the source rows are  specified  by
18       LINDXA.   The   destination of those rows are specified by  LINDXAU.  A
19       positive value of  LINDXAU indicates that the array destination  is  U,
20       and A otherwise.

ARGUMENTS

23       M       (local input)           const int
24               On  entry,  M  specifies the number of rows of A that should be
25               moved within A or copied into U. M must be at least zero.
26
27       N       (local input)           const int
28               On entry, N  specifies the length of rows of A that  should  be
29               moved within A or copied into U. N must be at least zero.
30
31       A       (local input/output)    double *
32               On  entry,  A points to an array of dimension (LDA,N). The rows
33               of this array specified by LINDXA should be moved within  A  or
34               copied into U.
35
36       LDA     (local input)           const int
37               On  entry,  LDA specifies the leading dimension of the array A.
38               LDA must be at least MAX(1,M).
39
40       U       (local input/output)    double *
41               On entry, U points to an array of dimension (LDU,N).  The  rows
42               of  A  specified by LINDXA are be copied within this array U at
43               the positions indicated by positive values of LINDXAU.
44
45       LDU     (local input)           const int
46               On entry, LDU specifies the leading dimension of the  array  U.
47               LDU must be at least MAX(1,M).
48
49       LINDXA  (local input)           const int *
50               On  entry,  LINDXA is an array of dimension M that contains the
51               local  row indexes  of  A  that should be moved within   A   or
52               or copied into U.
53
54       LINDXAU (local input)           const int *
55               On  entry,  LINDXAU  is an array of dimension  M that  contains
56               the local  row indexes of  U  where the rows of  A   should  be
57               copied at. This array also contains the  local row offsets in A
58               where some of the rows of A should be  moved  to.   A  positive
59               value  of   LINDXAU[i]  indicates that the row  LINDXA[i]  of A
60               should be copied into U at the position  LINDXAU[i];  otherwise
61               the  row   LINDXA[i]  of  A  should be moved  at  the  position
62               -LINDXAU[i] within A.
