*  \brief Sparse matrix vector multiplication using the BSR storage format.
*
*  \details
*  \p hipsparseXbsrmv multiplies the scalar \f$\alpha\f$ with a sparse
*  \f$m \times n\f$ matrix, defined in BSR storage format, and the dense vector \f$x\f$ and adds the
*  result to the dense vector \f$y\f$ that is multiplied by the scalar \f$\beta\f$, such that
*  \f[
*    y := \alpha \cdot op(A) \cdot x + \beta \cdot y,
*  \f]
*  with
*  \f[
*    op(A) = \left\{
*    \begin{array}{ll}
*        A,   & \text{if trans == HIPSPARSE_OPERATION_NON_TRANSPOSE}
*    \end{array}
*    \right.
*  \f]
*  and where \f$m = mb \times blockDim\f$ and \f$n= nb \times blockDim\f$.
*
*  \note
*  This function is non-blocking and executed asynchronously with respect to the host.
*  It can return before the actual computation has finished.
*
*  \note
*  Currently, only \p transA == \ref HIPSPARSE_OPERATION_NON_TRANSPOSE is supported.
