Function/Subroutine Documentation

subroutine dlacpy (characterUPLO, integerM, integerN, double precision, dimension( lda, * )A, integerLDA, double precision, dimension( ldb, * )B, integerLDB)

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

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).
