zlacpy(3S)

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, * )

IMPLEMENTATION
     These routines are part of the SCSL Scientific Library and can be loaded
     using either the -lscs or the -lscs_mp option.  The -lscs_mp option
     directs the linker to use the multi-processor version of the library.

     When linking to SCSL with -lscs or -lscs_mp, the default integer size is
     4 bytes (32 bits). Another version of SCSL is available in which integers
     are 8 bytes (64 bits).  This version allows the user access to larger
     memory sizes and helps when porting legacy Cray codes.  It can be loaded
     by using the -lscs_i8 option or the -lscs_i8_mp option. A program may use
     only one of the two versions; 4-byte integer and 8-byte integer library
     calls cannot be mixed.

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).
