Unclear to me what is supported. On v0.14.7
this happens:
julia> cubic_spline_interpolation([1,2,5],[4,2,4])
ERROR: MethodError: no method matching cubic_spline_interpolation(::Vector{Int64}, ::Vector{Int64})
Closest candidates are:
cubic_spline_interpolation(::AbstractRange, ::AbstractVector; bc, extrapolation_bc)

cubic_spline_interpolation(::Tuple{Vararg{AbstractRange, N}}, ::AbstractArray{T, N}; bc, extrapolation_bc) where {N, T}

julia> linear_interpolation([1,2,5],[4,2,4])
3-element extrapolate(interpolate((::Vector{Int64},), ::Vector{Int64}, Gridded(Linear())), Throw()) with element type Float64:
Ratios.SimpleRatio{Int64}(4, 1)
Ratios.SimpleRatio{Int64}(2, 1)
Ratios.SimpleRatio{Int64}(12, 3)
Maybe this is just a problem of wording
The Readme and the documentation tells me that "Currently this package supports [...] irregular grids." I interpreted this (wrongly as it turns out) that I can interpolate points arbitrarily scattered. It seems I'm not alone with this: this issue #552 clarifies that "irregular" means "rectilinear", and not arbitrary irregular.
Writing explicitly: "Currently this package supports interpolation on Cartesian and rectilinear grids" would have helped a lot.
