(S|D|C|Z)LASET¶

Single, double, single complex, and double complex LASET.

Description¶

Initializes diagonal and off-diagonal elements of a matrix.

LASET sets diagonal elements to $\beta$ . If UPLO is L, lower triangular elements off the diagonal of A are set to $\alpha$ and upper triangular elements are not accessed. If UPLO is U, upper triangular elements off the diagonal of A are set to $\alpha$ and lower triangular elements are not accessed. Otherwise, all off-diagonal elements are set to $\alpha$ .

LAPACK Interface¶

void slaset(const char *uplo, const qml_long *M, const qml_long *N,
    const float *ALPHA, const float *BETA, float *A, const qml_long *LDA);

void dlaset(const char *uplo, const qml_long *M, const qml_long *N,
    const double *ALPHA, const double *BETA, double *A, const qml_long *LDA);

void claset(const char *uplo, const qml_long *M, const qml_long *N,
    const qml_single_complex *ALPHA, const qml_single_complex *BETA,
    qml_single_complex *A, const qml_long *LDA);

void zlaset(const char *uplo, const qml_long *M, const qml_long *N,
    const qml_double_complex *ALPHA, const qml_double_complex *BETA,
    qml_double_complex *A, const qml_long *LDA);
