donuts-python 0.0.1rc1

Requirements

• Python 3.7 or later

• JDK 8 or later

Installation

pip install git+https://github.com/tueda/donuts-python

Example

>>> from donuts import *
>>> a = Polynomial('1 + x + y')
>>> b = Polynomial('1 + y + z')
>>> g = a + b
>>> g
Polynomial('2+z+2*y+x')
>>> ag = a * g
>>> bg = b * g
>>> ag.gcd(bg)  # must be equal to g
Polynomial('2+z+2*y+x')
>>> ag / bg  # same as RationalFunction(ag, bg)
RationalFunction('(1+y+x)/(1+z+y)')
>>> Polynomial('2*x^2 - 2*x^3 + 2*x^2*y - 2*x^3*y').factors
(Polynomial('-2'), Polynomial('x'), Polynomial('x'), Polynomial('-1+x'), Polynomial('1+y'))
