zlacp2: copies all or part of a real two-dimensional matrix A to a complex matrix B

NAME

ZLACP2 - copies all or part of a real two-dimensional matrix A to a complex matrix B

SYNOPSIS

SUBROUTINE ZLACP2(
UPLO, M, N, A, LDA, B, LDB )

    
CHARACTER UPLO

    
INTEGER LDA, LDB, M, N

    
DOUBLE PRECISION A( LDA, * )

    
COMPLEX*16 B( LDB, * )

PURPOSE

ZLACP2 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. = aqUaq: Upper triangular part
= aqLaq: 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) DOUBLE PRECISION array, dimension (LDA,N)
The m by n matrix A. If UPLO = aqUaq, only the upper trapezium is accessed; if UPLO = aqLaq, only the lower trapezium is accessed.
LDA (input) INTEGER
The leading dimension of the array A. LDA >= max(1,M).
B (output) COMPLEX*16 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).
