.SH DESCRIPTION
35 
\fB\&HPL_dlaswp04T\fR
36 
copies M0 columns of U into rows of A and replaces those
37 
columns of U with columns of W. In addition M1 - M0 columns of W  are
38 
copied into U.
39 
.SH ARGUMENTS
40 
.TP 8
41 
M0      (local input)           const int
42 
On entry, M0 specifies the number of columns of U that should
43 
be copied into A and replaced by columns of W.  M0 must be at
44 
least zero.
45 
.TP 8
46 
M1      (local input)           const int
47 
On entry, M1 specifies  the number of columnns of W that will
48 
be copied into U. M1 must be at least zero.
49 
.TP 8
50 
N       (local input)           const int
51 
On entry,  N  specifies the length of the columns of  U  that
52 
will be copied into rows of A. N must be at least zero.
53 
.TP 8
54 
U       (local input/output)    double *
55 
On entry,  U  points  to an array of dimension (LDU,*).  This
56 
array contains the columns that are to be copied into rows of
57 
A.
58 
.TP 8
59 
LDU     (local input)           const int
60 
On entry, LDU specifies the leading dimension of the array U.
61 
LDU must be at least MAX(1,N).
62 
.TP 8
63 
A       (local output)          double *
64 
On entry, A points to an array of dimension (LDA,N). On exit,
65 
the  rows of this array specified by  LINDXA  are replaced by
66 
columns of U indicated by LINDXAU.
67 
.TP 8
68 
LDA     (local input)           const int
69 
On entry, LDA specifies the leading dimension of the array A.
70 
LDA must be at least MAX(1,M0).
71 
.TP 8
72 
W0      (local input)           const double *
73 
On entry,  W0  is an array of size (M-1)*LDW+1, that contains
74 
the destination offset  in U where the columns of W should be
75 
copied.
76 
.TP 8
77 
W       (local input)           const double *
78 
On entry, W  is an array of size (LDW,M0+M1),  that  contains
79 
data to be copied into U.  For i in [M0..M0+M1),  the entries
80 
W(:,i) are copied into the column W0(i*LDW) of U.
81 
.TP 8
82 
LDW     (local input)           const int
83 
On entry, LDW specifies the leading dimension of the array W.
84 
LDW must be at least MAX(1,N+1).
85 
.TP 8
86 
LINDXA  (local input)           const int *
87 
On entry, LINDXA  is an array of dimension  M0 containing the
88 
local row indexes A into which columns of U are copied.
89 
.TP 8
90 
LINDXAU (local input)           const int *
91 
On entry, LINDXAU  is an array of dimension M0 that  contains
92 
the  local column indexes of  U  that should be copied into A
93 
and replaced by the columns of W.
