pysolvemath

Numeric Solver.

Usage

Real-valued Equations

from pysolvemath import solve_equations

def equations(x, y):
    x + y == 10
    2 * x == 8


res = solve_equations(equations)  
# res == {"x": 4.0, "y": 6.0}

By default, result are of type float, representing arbitrary real numbers.

Caller can use type hint of int and fractions.Fraction to specify unknown to "corerce" to that type.

from fractions import Fraction
from pysolvemath import solve_equations

def equations(x: int, y, z: Fraction):
    x + z == 1.5
    x**2 == 9
    y + z == 2

res = solve_equations(equations)
# res == {"x": 3, "y": 3.5, "z": -3/2}

As this is a numerical solver, this package only gets one (set of) root depending on starting point.

In the example above, we can also derive {"x": -3, "y": -2.5, "z": 9/2}, if we start the root finder from negative x.

User can proivde init_guess_func to specify the starting point.
