subroutine dlacpy (UPLO, M, N, A, LDA, B, LDB)
DLACPY copies all or part of one two-dimensional array to another.
DLACPY copies all or part of one two-dimensional array to another.
Purpose:
DLACPY copies all or part of a two-dimensional matrix A to another matrix B.
Parameters:
UPLO is 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
M is INTEGER
The number of rows of the matrix A. M >= 0.
N
N is INTEGER
The number of columns of the matrix A. N >= 0.
A
A is 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
LDA is INTEGER
The leading dimension of the array A. LDA >= max(1,M).
B
B is DOUBLE PRECISION array, dimension (LDB,N)
On exit, B = A in the locations specified by UPLO.
LDB
LDB is INTEGER
The leading dimension of the array B. LDB >= max(1,M).
