Shameless and direct clone of scipy's CloughTocher2DInterpolator for Julia
In particular, this package implements
scipy.interpolate.CloughTocher2DInterpolator .
using CloughTocher2DInterpolation
points = [0,0, 0,1, 1,0, 1,1, 2,0, 2,1]
ipoints = [0.5,0.5, 1.5,0.5]
# real
data = [1.0, 2.0, 3.0, 4.0, 5.0, 6.0]
interp = CloughTocher2DInterpolator(points, data)
interp(ipoints)
# complex
data = [1.0+2.0im, 2.0+3.0im, 3.0-1.0im, 4.0-0.5im, 5.0-3.0im, 6.0+5.0im]
interp = CloughTocher2DInterpolator(points, data)
interp(ipoints)
# interpolate data into preallocated array (will be resized if necessary)
result = zeros(eltype(data), length(data))
interp(ipoints, result)To make this work we ported/cloned/copied parts of the following files from the
scipy repo
( commit https://github.com/scipy/scipy/tree/445777598fc0e2cb96d9a506acb32b1d2655f80c ):
