//! The ndarray-interp crate provides interpolation algorithms
//! for interpolating _n_-dimesional data.
//!
//! [interp1d::Interp1D] provides functionality to interpolate _n_-dimensional
//! arrays along the first axis. The documentation of the different
//! interpolation methods provide examples.
//!
//! # Custom interpolation strategy
//! This crate defines the traits [`StrategyBuilder`](interp1d::StrategyBuilder)
//! and [`Strategy`](interp1d::Strategy) that allow implementation of user
//! defined interpolation algorithms.
//! see the `custom_strategy.rs` example.
