Description Usage Arguments Details Value Author(s)

A parallel implementation of the confluent hypergeometric function {}_{1}F_{1}(x ; a; b) using RcppParallel package

1 2	pkummer(x, a, b, relTol = 1e-06, nThreads = RcppParallel::defaultNumThreads())

`x,`	a, b numeric vectors of the same length
`relTol`	relative tolerance (default value `1e-6`) understood as the ratio of each term in the series relative to the sum

This function is implemented in C++. It is based on Pearson et al (2016). It implements the Taylor series method together with an asymtoptic expansion based on Watson's lemma. The actual implementation uses parallelFor from RcppParallel package together with a functor that computes confluent hypergeometric function for chunks of vectors x, a, b

Return a numeric vector with the values of the function
