CLACP2(3S)CLACP2(3S)NAME
CLACP2 - copie 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, * )
IMPLEMENTATION
These routines are part of the SCSL Scientific Library and can be loaded
using either the -lscs or the -lscs_mp option. The -lscs_mp option
directs the linker to use the multi-processor version of the library.
When linking to SCSL with -lscs or -lscs_mp, the default integer size is
4 bytes (32 bits). Another version of SCSL is available in which integers
are 8 bytes (64 bits). This version allows the user access to larger
memory sizes and helps when porting legacy Cray codes. It can be loaded
by using the -lscs_i8 option or the -lscs_i8_mp option. A program may use
only one of the two versions; 4-byte integer and 8-byte integer library
calls cannot be mixed.
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).
