scipy_port
This Dart package include some scipy functionalities which are directly ported from its source code.
Some minors modifications have been made, including the use of IntegerPointer and DoublePointer objects to replace C pointer's where they were used. You can check the oficial documentation
here
:https://docs.scipy.org/doc/scipy/reference/index.html although most of them are not ported (yet?).
The included utilities are mostly from scipy.special
and some from scipy.stats
:

Beta function

Gamma function

Hypergeometric function

Incomplete beta integral

Inverse of incomplete beta integral

Inverse of Normal distribution function

Evaluate polynomial

Psi (digamma) function

Student's t distribution CDF and it's inverse.
Feel free to contribute adding more functionality by making Pull requests. I will check and add them.
