ZLACP2 - copie all or part of a real two-dimensional
matrix 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
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).
