DLACPY(3)      LAPACK routine of NEC Numeric Library Collection      DLACPY(3)



NAME
       DLACPY

SYNOPSIS
       SUBROUTINE DLACPY (UPLO, M, N, A, LDA, B, LDB)



PURPOSE
            DLACPY copies all or part of a two-dimensional matrix A to another
            matrix B.




ARGUMENTS
           UPLO      (input)
                     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         (input)
                     M is INTEGER
                     The number of rows of the matrix A.  M >= 0.

           N         (input)
                     N is INTEGER
                     The number of columns of the matrix A.  N >= 0.

           A         (input)
                     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       (input)
                     LDA is INTEGER
                     The leading dimension of the array A.  LDA >= max(1,M).

           B         (output)
                     B is DOUBLE PRECISION array, dimension (LDB,N)
                     On exit, B = A in the locations specified by UPLO.

           LDB       (input)
                     LDB is INTEGER
                     The leading dimension of the array B.  LDB >= max(1,M).
