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 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) 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).
