DLACPY
November 2006
Purpose
DLACPY copies all or part of a two-dimensional matrix A to another
matrix B.
matrix B.
Arguments
| UPLO |
(input) CHARACTER*1
Specifies the part of the matrix A to be copied to B.
= 'U': Upper triangular part = 'L': Lower triangular part Otherwise: All of the matrix A |
| M |
(input) INTEGER
The number of rows of the matrix A. M >= 0.
|
| N |
(input) INTEGER
The number of columns of the matrix A. N >= 0.
|
| A |
(input) DOUBLE PRECISION array, dimension (LDA,N)
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 |
(input) INTEGER
The leading dimension of the array A. LDA >= max(1,M).
|
| B |
(output) DOUBLE PRECISION array, dimension (LDB,N)
On exit, B = A in the locations specified by UPLO.
|
| LDB |
(input) INTEGER
The leading dimension of the array B. LDB >= max(1,M).
