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 twodimensional array to another.
Purpose:

DLACPY copies all or part of a twodimensional 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
MM is INTEGER The number of rows of the matrix A. M >= 0.
NN is INTEGER The number of columns of the matrix A. N >= 0.
AA 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.
LDALDA is INTEGER The leading dimension of the array A. LDA >= max(1,M).
BB is DOUBLE PRECISION array, dimension (LDB,N) On exit, B = A in the locations specified by UPLO.
LDBLDB is INTEGER The leading dimension of the array B. LDB >= max(1,M).
