Detailed Description

template<uint32_t Dim, uint32_t Degree, bool InteractionOnly>
class o2::gpu::MultivariatePolynomialHelper< Dim, Degree, InteractionOnly >

Helper struct for evaluating a multidimensional polynomial using compile time evaluated formula Compile time method to extract the formula is obtained from run time method (check combination_with_repetiton() and evalPol()) by performing all loops during compile time and replacing the array to keep track of the dimensions for given term (pos[FMaxdegree + 1]) to a simple uint32_t called Pos where each digit represents the dimension for a given term e.g. pos = 2234 -> x[2]*x[2]*x[3]*x[4]
