NAME

6       HPL_dlaswp01T - copies rows of A into itself and into U.

SYNOPSIS

9       #include "hpl.h"
10
11       void  HPL_dlaswp01T(  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_dlaswp01T  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. Rows of A are stored as columns in U.

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,M).  The  rows
42               of  A  specified by  LINDXA  are copied within this array  U at
43               the  positions indicated by positive values  of  LINDXAU.   The
44               rows of A are stored as columns in U.
45
46       LDU     (local input)           const int
47               On  entry,  LDU specifies the leading dimension of the array U.
48               LDU must be at least MAX(1,N).
49
50       LINDXA  (local input)           const int *
51               On entry, LINDXA is an array of dimension M that  contains  the
52               local   row  indexes  of  A  that should be moved within  A  or
53               or copied into U.
54
55       LINDXAU (local input)           const int *
56               On entry, LINDXAU  is an array of dimension  M  that   contains
57               the  local   row indexes of  U  where the rows of  A  should be
58               copied at. This array also contains the  local row offsets in A
59               where  some  of  the  rows of A should be moved to.  A positive
60               value of  LINDXAU[i]  indicates that the row  LINDXA[i]   of  A
61               should  be  copied into U at the position LINDXAU[i]; otherwise
62               the row  LINDXA[i]  of  A  should be moved  at   the   position
63               -LINDXAU[i] within A.
