Interpolations
NEWS v0.9 was a breaking release. See the news for details on how to update.
This package implements a variety of interpolation schemes for the Julia language. It has the goals of ease-of-use, broad algorithmic support, and exceptional performance.
Currently this package's support is best for B-splines and also supports irregular grids. However, the API has been designed with intent to support more options. Pull-requests are more than welcome! It should be noted that the API may continue to evolve over time.
Other interpolation packages for Julia include:
Some of these packages support methods that Interpolations does not, so if you can't find what you need here, check one of them or submit a pull request here.
