public class DBeta extends AbstractBivariateRealFunction
Beta function w.r.t x, \({\partial \over \partial x} \mathrm{B}(x, y)\).
\[
{\partial \over \partial x} \mathrm{B}(x, y) = \mathrm{B}(x, y) (\psi(x) - \psi(x + y))
\]
where \(x > 0, y > 0\), \(\psi\) is the Digamma function.BetaFunction.EvaluationException| Constructor and Description |
