(S|D)GER¶

Single and double GER.

Description¶

Computes the rank-1 operation:

$A \assign \alpha x * \trans{y} + A$

BLAS Interface¶

void sger(const qml_long *M, const qml_long *N, const float *ALPHA,
          const float *X, const qml_long *INCX, const float *Y,
          const qml_long *INCY, float *A, const qml_long *LDA);

void dger(const qml_long *M, const qml_long *N, const double *ALPHA,
          const double *X, const qml_long *INCX, const double *Y,
          const qml_long *INCY, double *A, const qml_long *LDA);

CBLAS Interface¶

void cblas_sger(const CBLAS_ORDER ORDER, const qml_long M, const qml_long N,
                const float ALPHA, const float *X, const qml_long INCX,
                const float *Y, const qml_long INCY, float *A,
                const qml_long LDA);

void cblas_dger(const CBLAS_ORDER ORDER, const qml_long M, const qml_long N,
                const double ALPHA, const double *X, const qml_long INCX,
                const double *Y, const qml_long INCY, double *A,
                const qml_long LDA);
