NAME

ZLACP2 - copie all or part of a real two-dimensional ma

trix A to a complex matrix B

SYNOPSIS

SUBROUTINE ZLACP2( UPLO, M, N, A, LDA, B, LDB )
    CHARACTER      UPLO
    INTEGER        LDA, LDB, M, N
    DOUBLE         PRECISION A( LDA, * )
    COMPLEX*16     B( LDB, * )

PURPOSE

ZLACP2 copies all or part of a real two-dimensional matrix

A to a complex 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) DOUBLE PRECISION array, dimension (LDA,N)

The m by n matrix A. If UPLO = 'U', only the up

per trapezium is accessed; if UPLO = 'L', only the lower trapezi

um 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).
