* \brief Scale a sparse vector and add it to a scaled dense vector.
*
* \details
* \p hipsparseAxpby multiplies the sparse vector \f$x\f$ with scalar \f$\alpha\f$ and
* adds the result to the dense vector \f$y\f$ that is multiplied with scalar
* \f$\beta\f$, such that
*
* \f[
* y := \alpha \cdot x + \beta \cdot y
* \f]
*
* \code{.c}
* for(i = 0; i < size; ++i)
* {
* y[i] = beta * y[i]
* }
* for(i = 0; i < nnz; ++i)
* {
* y[xInd[i]] += alpha * xVal[i]
* }
* \endcode
*
* \p hipsparseAxpby supports the following precision data types for the sparse and dense vectors \f$x\f$ and
* \f$y\f$ and compute types for the scalars \f$\alpha\f$ and \f$\beta\f$.
