Adding z to interpolation

[journeytosilius]

Hi, thanks for the lib !

I do this on python and trying to port it to C++ now:

# Interpolate
rbf = scipy.interpolate.Rbf(x, y, z, function='linear')
zi = rbf(xi, yi)

the scipy interpolate function accepts up to four inputs for the interpolation, in my case I'm using x,y and z Is it possible to replicate this with rbf_interpolator.SetData() ?

Thanks

Yes. The method SetData() takes X and y as inputs. The input X is a matrix where each column represents a data point. This can include any number of data points. This is similar to scipy https://docs.scipy.org/doc/scipy/reference/generated/scipy.interpolate.RBFInterpolator.html .
