NAME
     zlacpy - copie all or part of a two-dimensional matrix A  to
     another matrix B

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

     CHARACTER UPLO

     INTEGER LDA, LDB, M, N

     COMPLEX*16 A( LDA, * ), B( LDB, * )



     #include <sunperf.h>

     void zlacpy(char uplo, int m, int n, doublecomplex *za,  int
               lda, doublecomplex *zb, int ldb) ;

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

     B         (output) COMPLEX*16 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).
