pyratapprox: Approximation by rational functions
pyratapprox provides a Python interface to Julia's RationalFunctionApproximation library, enabling efficient computation of rational function approximations and interpolations.
Installation
pip install pyratapprox
Note: Requires Julia to be installed. The required Julia packages will be installed automatically on first use.
Quick Start
import numpy as np
from pyratapprox import approximate, unitinterval, AAA
# Approximate a function on the unit interval [-1, 1]
f = approximate(np.sin, unitinterval, method=AAA)
# Evaluate the approximation
y = f(0.5)
# Get poles and residues
poles = f.poles()
poles, residues = f.residues()
