Web14 Mar 2024 · Bessel function, also called cylinder function, any of a set of mathematical functions systematically derived around 1817 by the German astronomer Friedrich Wilhelm Bessel during an investigation of solutions of one of Kepler’s equations of planetary motion. Web30 Sep 2012 · The main feature of the scipy.special package is the definition of numerous special functions of mathematical physics. Available functions include airy, elliptic, bessel, gamma, beta, hypergeometric, parabolic cylinder, mathieu, spheroidal wave, struve, and kelvin. There are also some low-level stats functions that are not intended for general ...

These functions are unnecessary because of symmetries in the beta function. One could define betaincc(a, b, x) as betainc(b, a, 1-x) and betainccinv(a, b, x) as betaincinv(b, a, 1-x). See also.
