Parameters

UPLO  String

(input) CHARACTER*1 Specifies the part of the matrix A to be set. = 'U': Upper triangular part is set; the strictly lower triangular part of A is not changed. = 'L': Lower triangular part is set; the strictly upper triangular part of A is not changed. Otherwise: All of the matrix A is set.

M  Int32

(input) INTEGER The number of rows of the matrix A. M .GE. 0.

N  Int32

(input) INTEGER The number of columns of the matrix A. N .GE. 0.

ALPHA  Double

(input) DOUBLE PRECISION The constant to which the offdiagonal elements are to be set.

BETA  Double

(input) DOUBLE PRECISION The constant to which the diagonal elements are to be set.

A  Double

(input/output) DOUBLE PRECISION array, dimension (LDA,N) On exit, the leading m-by-n submatrix of A is set as follows: if UPLO = 'U', A(i,j) = ALPHA, 1.LE.i.LE.j-1, 1.LE.j.LE.n, if UPLO = 'L', A(i,j) = ALPHA, j+1.LE.i.LE.m, 1.LE.j.LE.n, otherwise, A(i,j) = ALPHA, 1.LE.i.LE.m, 1.LE.j.LE.n, i.ne.j, and, for all UPLO, A(i,i) = BETA, 1.LE.i.LE.min(m,n).

offset_a  Int32

 

LDA  Int32

(input) INTEGER The leading dimension of the array A. LDA .GE. max(1,M).
