Function/Subroutine Documentation
subroutine claset (character UPLO, integer M, integer N, complex ALPHA, complex BETA, complex, dimension( lda, * ) A, integer LDA)CLASET initializes the off-diagonal elements and the diagonal elements of a matrix to given values​. Purpose: CLASET initializes a 2-D array A to BETA on the diagonal and ALPHA on the offdiagonals.Parameters: UPLO UPLO is CHARACTER*1 Specifies the part of the matrix A to be set. = 'U': Upper triangular part is set. The lower triangle is unchanged. = 'L': Lower triangular part is set. The upper triangle is unchanged. Otherwise: All of the matrix A is set.
M M is INTEGER On entry, M specifies the number of rows of A.
N N is INTEGER On entry, N specifies the number of columns of A.
ALPHA ALPHA is COMPLEX All the offdiagonal array elements are set to ALPHA.
BETA BETA is COMPLEX All the diagonal array elements are set to BETA.
A A is COMPLEX array, dimension (LDA,N) On entry, the m by n matrix A. On exit, A(i,j) = ALPHA, 1 <= i <= m, 1 <= j <= n, i.ne.j; A(i,i) = BETA , 1 <= i <= min(m,n)
LDA LDA is INTEGER The leading dimension of the array A. LDA >= max(1,M).Author: Univ​. of Tennessee Univ​. of California Berkeley Univ​. of Colorado Denver NAG Ltd​. Date: December 2016 Definition at line 108 of file claset​.f​.
