ncpy 0.1.5

A Python package for numerical computing, including root-finding, interpolation, integration, differentiation, and linear system solvers.

ncpy

ncpy — Numerical Computing in Python.

ncpy is a compact, educational Python library that implements common numerical methods for courses and quick prototyping.
It is built on top of NumPy and (optionally) SciPy, and provides easy-to-use functions for root finding, interpolation, approximation, integration, differentiation, and solving linear systems.

Quick Example

from ncpy import roots

Example: Newton–Raphson method

f = lambda x: x**2 - 2 df = lambda x: 2*x

root = roots.newton_raphson(f, df, x0=1.0) print("Root:", root)
