* matrix \f$A\f$, defined in BSR storage format, and the column-oriented dense \f$k \times n\f$
|
|
* matrix \f$B\f$ and adds the result to the column-oriented dense \f$m \times n\f$ matrix \f$C\f$ that
|
|
* is multiplied by the scalar \f$\beta\f$, such that
|
|
* \f[
|
|
* C := \alpha \cdot op(A) \cdot op(B) + \beta \cdot C,
|
|
* \f]
|
|
