Synopsis
Functions
subroutine clacp2 (uplo, m, n, a, lda, b, ldb)
CLACP2 copies all or part of a real two-dimensional array to a complex array.
subroutine zlacp2 (uplo, m, n, a, lda, b, ldb)

Detailed Description
Function Documentation
subroutine clacp2 (character uplo, integer m, integer n, real, dimension( lda, * ) a, integer lda, complex, dimension( ldb, * ) b, integer ldb)
CLACP2 copies all or part of a real two-dimensional array to a complex array.
Purpose:
CLACP2 copies all or part of a real two-dimensional matrix A to a complex matrix B.
- Parameters
UPLO
UPLO is 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
M is INTEGER The number of rows of the matrix A. M >= 0.
N
N is INTEGER The number of columns of the matrix A. N >= 0.
A
A is 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
LDA is INTEGER The leading dimension of the array A. LDA >= max(1,M).
B
B is COMPLEX array, dimension (LDB,N) On exit, B = A in the locations specified by UPLO.
LDB
LDB is INTEGER The leading dimension of the array B. LDB >= max(1,M).
