Special Functions

Bessel, Legendre, elliptic, error, gamma, and other functions

Special functions are a group of well-known mathematical functions that frequently arise in real-world applications. You can use them to calculate Bessel functions, beta functions, gamma functions, error functions, elliptic integrals, and more. Since the properties of these functions have been studied extensively, you can find more information about many of them in the NIST Digital Library of Mathematical Functions.
