*  \brief Sparse matrix vector multiplication using HYB storage format
*
*  \details
*  \p hipsparseXhybmv multiplies the scalar \f$\alpha\f$ with a sparse \f$m \times n\f$
*  matrix, defined in HYB 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 transA == HIPSPARSE_OPERATION_NON_TRANSPOSE}
*    \end{array}
*    \right.
*  \f]
*
*  \note
*  This function is non blocking and executed asynchronously with respect to the host.
*  It may return before the actual computation has finished.
*
*  \note
*  Currently, only \p transA == \ref HIPSPARSE_OPERATION_NON_TRANSPOSE is supported.
*
*  @param[in]
*  handle      handle to the hipsparse library context queue.
*  @param[in]
*  transA      matrix operation type.
*  @param[in]
*  alpha       scalar \f$\alpha\f$.
*  @param[in]
*  descrA      descriptor of the sparse HYB matrix. Currently, only
*              \ref HIPSPARSE_MATRIX_TYPE_GENERAL is supported.
*  @param[in]
*  hybA        matrix in HYB storage format.
*  @param[in]
*  x           array of \p n elements (\f$op(A) == A\f$) or \p m elements
*              (\f$op(A) == A^T\f$ or \f$op(A) == A^H\f$).
*  @param[in]
*  beta        scalar \f$\beta\f$.
*  @param[inout]
*  y           array of \p m elements (\f$op(A) == A\f$) or \p n elements
*              (\f$op(A) == A^T\f$ or \f$op(A) == A^H\f$).
*
*  \retval     HIPSPARSE_STATUS_SUCCESS the operation completed successfully.
*  \retval     HIPSPARSE_STATUS_INVALID_VALUE \p handle, \p descrA, \p alpha,
*              \p hybA, \p x, \p beta or \p y is invalid.
