Package-extensions

In Julia 1.9 Package Extensions were introduced. Unfold.jl is making use of them in four ways. Prior to using some functionality, you have to add + load specific package(s) for the functionality to be available. The reason for this is, that if you don't need e.g. GPU-support, you also will not need to install it.

GPU: Krylov,CUDA

To use gpu support as described in @Ref(custom_solvers) you have to:

using Krylov,CUDA
using Unfold

RobustSolvers.jl

To use robust (outlier-"safe") solvers support as described in @Ref(custom_solvers) you have to:

import RobustSolvers
using Unfold

Non-linear effects: BSplineKit.jl

Finally to use non-linear effects/splines like in @formula 0~1+spl(continuous,5) you have to use:

import BSplineKit
using Unfold
