classes

a small repo to experiment with simple computer algebra. a place where I kind of test out ideas.

how to install system

1. clone repo: git clone https://github.com/Jobhdez/classes.git
2. run tests: pytest -q tests.py
3. load files: exec(open(<file>).read())

dependencies

1. pip3 install pytest
2. brew install git for mac
3. sudo apt install git for Ubuntu

examples

Linear Algebra

for the linear algebra system look at the tests for examples.

Polynomials

>>> exec(open('poly.py').read())
>>> poly = Poly(3,2,1)
>>> poly
Polynomial(3, 2, 1)
>>> add1 = Addition.compute(poly, poly)
>>> add1
Polynomial(6, 4, 2)
>>> composite = CompositeAddition(poly, poly, poly)
>>> composite.compute()


>>> sub = Subtraction(poly, poly)
>>> sub
<__main__.Subtraction object at 0x105178a60>
>>> sub.compute()
Polynomial(0, 0, 0)
>>> op = CompositeSubtraction(sub.compute(), sub.compute(), sub.compute())
>>> op.compute()
Polynomial(0, 0, 0)
>>> sub.poly
Polynomial(7, 8, 9)
>>> poly1 = sub.poly
>>> poly2 = sub.poly2
>>> sub_composite = CompositeSubtraction(poly, poly, poly2)
>>> sub_composite.compute()
Polynomial(-7, -8, -9)

>>> poly = Poly(5,4,3,2,1)
>>> eval_poly(poly, 3)
Integer(547)

>>> poly = Poly(4,3,2,1)
>>> deriv = Deriv(poly)
>>> deriv.compute()
Polynomial(12, 6, 2)
