# ninterp

The `ninterp` crate provides [multivariate interpolation](https://en.wikipedia.org/wiki/Multivariate_interpolation#Regular_grid) over a regular, sorted, nonrepeating grid of any dimensionality. A variety of interpolation strategies are implemented, however more are likely to be added. Extrapolation beyond the range of the supplied coordinates is supported for 1-D linear interpolators, using the slope of the nearby points.

There are hard-coded interpolators for lower dimensionalities (up to N = 3) for better runtime performance.

All interpolation is handled through instances of the Interpolator enum, with the selected tuple variant containing relevant data. Interpolation is executed by calling Interpolator::interpolate.

## Feature Flags
- `serde`: support for serde

## Getting Started

See the Interpolator enum documentation for examples and notes on usage.
