pytspack

A high-performance Python wrapper for Robert J. Renka's C library for tension spline curve fitting (TSPACK).

Installation

This package requires a C compiler and NumPy to be installed.

Standard Installation

For most users, a simple pip install from the repository root will work:

pip install .

This command compiles the C extension and installs the pytspack package into your active Python environment.

Editable Mode

For development, install the package in editable mode:

pip install -e .

Usage

import numpy as np
from pytspack import TsPack

x = np.array([0.0, 1.0, 2.0, 3.0])
y = np.array([0.0, 1.0, 0.0, 1.0])

tspack = TsPack()
interpolator = tspack.interpolate(x, y, tension=2.0)

test_points = np.linspace(0, 3, 100)
results = interpolator(test_points)
