man zlacpy (Fonctions bibliothèques) - copie all or part of a two-dimensional matrix A to another matrix B
NAME
ZLACPY - copie all or part of a two-dimensional matrix A to another matrix B
SYNOPSIS
- SUBROUTINE ZLACPY(
- UPLO, M, N, A, LDA, B, LDB )
- CHARACTER UPLO
- INTEGER LDA, LDB, M, N
- COMPLEX*16 A( LDA, * ), B( LDB, * )
PURPOSE
ZLACPY copies all or part of a two-dimensional matrix A to another 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) COMPLEX*16 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*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).
