3-parameter beta distribution of the second kind in Matlab

Matlab class for a 3-parameter beta distribution of the second kind. Written for the paper https://arxiv.org/pdf/1911.12835.pdf .

The 3-parameter beta distribution of the second kind is a parametric probability distribution.

We use the parametrization and variable names that are also used in 10.1016/S0029-8018(98)00022-5, equation 5 .

* The class file Beta3pSecondKind.m provides all functionality.
* The file testBeta3pSecondKind.m tests the functioality and serves as an example.
