NAME

6       HPL_dlaswp04N - copy rows of U in A and replace them with columns of W.

SYNOPSIS

9       #include "hpl.h"
10
11       void  HPL_dlaswp04N(  const int M0, const int M1, const int N, double *
12       U, const int LDU, double * A, const int LDA, const double *  W0,  const
13       double * W, const int LDW, const int * LINDXA, const int * LINDXAU );

DESCRIPTION

16       HPL_dlaswp04N  copies  M0 rows of U into A and replaces those rows of U
17       with columns of W. In addition M1 - M0 columns of  W  are  copied  into
18       rows of U.

ARGUMENTS

21       M0      (local input)           const int
22               On  entry,  M0 specifies the number of rows of U that should be
23               copied into  A  and replaced by columns of  W.  M0 must  be  at
24               least zero.
25
26       M1      (local input)           const int
27               On  entry,  M1 specifies the number of columns of W that should
28               be copied into rows of U. M1 must be at least zero.
29
30       N       (local input)           const int
31               On entry, N specifies the length of the rows of U  that  should
32               be copied into A. N must be at least zero.
33
34       U       (local input/output)    double *
35               On  entry,   U  points to  an array of dimension (LDU,N).  This
36               array contains the rows that are to be copied into A.
37
38       LDU     (local input)           const int
39               On entry, LDU specifies the leading dimension of the  array  U.
40               LDU must be at least MAX(1,M1).
41
42       A       (local output)          double *
43               On  entry,  A points to an array of dimension (LDA,N). On exit,
44               the  rows of this array specified by  LINDXA  are  replaced  by
45               rows of U indicated by LINDXAU.
46
47       LDA     (local input)           const int
48               On  entry,  LDA specifies the leading dimension of the array A.
49               LDA must be at least MAX(1,M0).
50
51       W0      (local input)           const double *
52               On entry,  W0  is an array of size (M-1)*LDW+1,  that  contains
53               the  destination  offset  in U where the columns of W should be
54               copied.
55
56       W       (local input)           const double *
57               On entry, W  is an array of size (LDW,M0+M1),   that   contains
58               data  to  be copied into U.  For i in [M0..M0+M1),  the entries
59               W(:,i) are copied into the row W0(i*LDW) of U.
60
61       LDW     (local input)           const int
62               On entry, LDW specifies the leading dimension of the  array  W.
63               LDW must be at least MAX(1,N+1).
64
65       LINDXA  (local input)           const int *
66               On  entry,  LINDXA  is an array of dimension  M0 containing the
67               local row indexes A into which rows of U are copied.
68
69       LINDXAU (local input)           const int *
70               On entry, LINDXAU  is an array of dimension M0  that   contains
71               the  local   row indexes of  U that should be copied into A and
72               replaced by the columns of W.
