# Special Functions [![Build Status][travis-svg]][travis-url]
The library provides [special functions][1] and currently includes:
* `erf` — the error function,
* `erfc` — the complementary error function,
* `inc_beta` — the incomplete beta function,
* `inv_inc_beta` — the inverse of the incomplete beta function,
* `ln_beta` — the natural logarithm of the beta function, and
* `ln_gamma` — the natural logarithm of the gamma function.
