NAME

lacp2 - lacp2: general matrix, convert real to complex

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)
ZLACP2 copies all or part of a real two-dimensional array to a complex array.

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.
= ā€™Uā€™: Upper triangular part
= ā€™Lā€™: 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 = ā€™Uā€™, only the upper trapezium
is accessed; if UPLO = ā€™Lā€™, 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).

A

A is DOUBLE PRECISION array, dimension (LDA,N)
The m by n matrix A. If UPLO = ā€™Uā€™, only the upper trapezium
is accessed; if UPLO = ā€™Lā€™, only the lower trapezium is
accessed.

LDA

LDA is INTEGER
The leading dimension of the array A. LDA >= max(1,M).
