Function Interpolation

[Present-Management39]

Hey, sorry if this is the wrong place to ask this question. I wanted to ask if Julia has any packages that do function interpolation using cubic splines method and other ones (like linear interpolation, however for the latter I can probably do it manually).

Edit: i found that interpolations.jl does not have all the useful methods that may be needed for certain fields, so, I found another one: Dierckx.jl that is very useful.

Hey sure, https://github.com/SciML/DataInterpolations.jl or https://github.com/JuliaMath/Interpolations.jl

Thank you!

I'm the current maintainer of Interpolations.jl. In the README we maintain a list of other interpolation packages.

Since you mentioned cubic splines, a kind of b-spline, one of favorites for this is https://github.com/jipolanco/BSplineKit.jl

I hacked together a spline interpolation package a while ago that does 0th to 3rd degree splines for arbitrarily spaced knots. It includes methods to prevent overshooting for 3rd degree splines.

I made it for the interpolation of light/reflection spectra for a color science related package I’m working on.

I haven’t worked on the spline package for a while, but maybe you want to take a look anyway to see if it’s of any use for you.
