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).
