nrp 0.0.1.1

Package for root computation of math functions

nrp

This is a small package for computing roots of a given function using newton-raphson method.

The user needs to supply an initial root guess, the function as well as the first derivative of the function as callbacks.

Usage

(We are actively adding support for passing functions as callback.) Example:

from nrp import newton_raphson
from lpython import f64, i32


def check():
    x0: f64 = 20.0
    c: f64 = 3.0
    maxiter: i32 = 20
    x: f64
    x = newton_raphson(x0, c, maxiter)
    assert abs(x - 3.0) < 1e-5

check()
