ITDS interpolation Documentation

A standalone NumPy-only interpolation package with APIs inspired by IMSL.

Interpolation tools without the SciPy dependency chain

interpolation packages the spline, grid, surface, and least-squares routines extracted from ITDS into a focused NumPy-only library. The docs below are organized for fast onboarding: install, run a minimal spline, then move into examples or the API reference.

Open quick start Browse API reference

NumPy-onlyNo SciPy or compiled extension dependency.

1D to 3DPiecewise polynomial, spline, surface, and tensor-grid routines.

IMSL-styleFunction families aligned with legacy engineering workflows.

TestedUnit and integration coverage shipped with the package.

Install and run

Start with editable install commands and a minimal spline workflow.

Explore examples

Use targeted scripts for cubic splines, B-splines, surfaces, and IMSL parity sweeps.

Use the API directly

Jump into the public package reference once you know the routine family you need.

Recommended path: install the package, run the quick start, then use the examples page to find the closest routine family before dropping into the API reference.
