NAME DLACPY - copy all or part of a two-dimensional matrix A to another matrix B SYNOPSIS SUBROUTINE DLACPY( UPLO, M, N, A, LDA, B, LDB ) CHARACTER UPLO INTEGER LDA, LDB, M, N DOUBLE PRECISION A( LDA, * ), B( LDB, * ) PURPOSE DLACPY copies all or part of a two-dimensional matrix A to another 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).
