CLACP2(1) LAPACK auxiliary routine (version 3.2) CLACP2(1)NAME
CLACP2 - copies all or part of a real two-dimensional matrix A to a
complex matrix B
SYNOPSIS
SUBROUTINE CLACP2( UPLO, M, N, A, LDA, B, LDB )
CHARACTER UPLO
INTEGER LDA, LDB, M, N
REAL A( LDA, * )
COMPLEX B( LDB, * )
PURPOSE
CLACP2 copies all or part of a real two-dimensional matrix A to a com‐
plex 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) REAL 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 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).
