Description Usage Arguments Details Value Author(s)

Partial implementation of the confluent hypergeometric function {}_{1}F_{1}(x ; a; b)

1 2	kummer(x, a, b, relTol = 1e-08, 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
`nThreads`	number (default the number of all cores, including logical cores) to use for computation

This function is implemented in C++. It is based on Pearson et al (2016). It only implements the Taylor series method together with an asymtoptic expansion based on Watson's lemma

Return a numeric vector with the values of the function
