Description
The routine copies all or part of a real matrix
A
to another matrix
B
.
Input Parameters
uplo
CHARACTER*1
.
Specifies the part of the matrix
A
to be copied to
B
.
If
uplo
=
'U'
, the upper triangular part of
A
;
if
uplo
=
'L'
, the lower triangular part of
A
.
Otherwise, all of the matrix
A
is copied.
m
INTEGER
.
The number of rows in the matrix
A
(
m
0
).
n
INTEGER
.
The number of columns in
A
(
n
0
).
a
REAL
for
clacp2
DOUBLE PRECISION
for
zlacp2
Array, size at least
(
lda
,
n
)
, contains the
m
-by-
n
matrix
A
.
If
uplo
=
'U'
, only the upper triangle or trapezoid is accessed; if
uplo
=
'L'
, only the lower triangle or trapezoid is accessed.
lda
INTEGER
.
The leading dimension of
a
;
lda
max(1,
m
)
.
ldb
INTEGER
.
The leading dimension of the output array
b
;
ldb
max(1,
m
)
.
Output Parameters
b
COMPLEX
for
clacp2
DOUBLE COMPLEX
for
zlacp2
.
Array, size
(
ldb
,
n
)
.
On exit,
B
=
A
in the locations specified by
uplo
.
info
INTEGER
.
If
info
= 0
, the execution is successful.
If
info
< 0
, the
i
-th parameter had an illegal value.
If
info
= -1011
, memory allocation error occurred.
