Function/Subroutine Documentation

subroutine dlacpy (character UPLO, integer M, integer N, double precision, dimension( lda, * ) A, integer LDA, double precision, dimension( ldb, * ) B, integer LDB)

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).
