void slaset(const char *uplo, const INT m, const INT n, const f32 alpha, const f32 beta, f32 *restrict A, const INT lda)#

SLASET initializes an m-by-n matrix A to BETA on the diagonal and ALPHA on the offdiagonals.

Parameters

in
uplo

Specifies the part of 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.

in
m

The number of rows of A. m >= 0.

in
n

The number of columns of A. n >= 0.

in
alpha

The constant to which the offdiagonal elements are set.

in
beta

out
A

Double precision array, dimension (lda, n). On exit, the leading m-by-n submatrix of A is set as described above.

in
lda

The leading dimension of A. lda >= max(1, m).
