Function/Subroutine Documentation

subroutine zlacpy (character uplo, integer m, integer n, complex*16, dimension( lda, * ) a, integer lda, complex*16, dimension( ldb, * ) b, integer ldb)

ZLACPY copies all or part of one two-dimensional array to another.  

Purpose:

 ZLACPY 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 COMPLEX*16 array, dimension (LDA,N)
          The m by n matrix A.  If UPLO = 'U', only the upper trapezium
          is accessed; if UPLO = 'L', only the lower trapezium is
          accessed.

LDA

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

B

          B is COMPLEX*16 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).
