.SH DESCRIPTION
27 
\fB\&HPL_dlaswp01N\fR
28 
copies  scattered rows  of  A  into itself  and into an
29 
array  U.  The row offsets in  A  of the source rows are specified by
30 
LINDXA.  The  destination of those rows are specified by  LINDXAU.  A
31 
positive value of  LINDXAU indicates that the array destination is U,
32 
and A otherwise.
33 
.SH ARGUMENTS
34 
.TP 8
35 
M       (local input)           const int
36 
On entry, M  specifies the number of rows of A that should be
37 
moved within A or copied into U. M must be at least zero.
38 
.TP 8
39 
N       (local input)           const int
40 
On entry, N  specifies the length of rows of A that should be
41 
moved within A or copied into U. N must be at least zero.
42 
.TP 8
43 
A       (local input/output)    double *
44 
On entry, A points to an array of dimension (LDA,N). The rows
45 
of this array specified by LINDXA should be moved within A or
46 
copied into U.
47 
.TP 8
48 
LDA     (local input)           const int
49 
On entry, LDA specifies the leading dimension of the array A.
50 
LDA must be at least MAX(1,M).
51 
.TP 8
52 
U       (local input/output)    double *
53 
On entry, U points to an array of dimension (LDU,N). The rows
54 
of A specified by LINDXA are be copied within this array U at
55 
the positions indicated by positive values of LINDXAU.
56 
.TP 8
57 
LDU     (local input)           const int
58 
On entry, LDU specifies the leading dimension of the array U.
59 
LDU must be at least MAX(1,M).
60 
.TP 8
61 
LINDXA  (local input)           const int *
62 
On entry, LINDXA is an array of dimension M that contains the
63 
local  row indexes  of  A  that should be moved within  A  or
64 
or copied into U.
65 
.TP 8
66 
LINDXAU (local input)           const int *
67 
On entry, LINDXAU  is an array of dimension  M that  contains
68 
the local  row indexes of  U  where the rows of  A  should be
69 
copied at. This array also contains the  local row offsets in
70 
A where some of the rows of A should be moved to.  A positive
71 
value of  LINDXAU[i]  indicates that the row  LINDXA[i]  of A
72 
should be copied into U at the position LINDXAU[i]; otherwise
73 
the row  LINDXA[i]  of  A  should be moved  at  the  position
74 
-LINDXAU[i] within A.
