man clacp2 (Fonctions bibliothèques) - copie all or part of a real two-dimensional matrix A to a complex matrix B
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, * )
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).
