CloughTocher2DInterpolation

Shameless and direct clone of scipy's CloughTocher2DInterpolator for Julia

In particular, this package implements scipy.interpolate.CloughTocher2DInterpolator .

Usage

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)
