**NAME**

LAPACK-3 - 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).
