2d Interpolation In Python With Random Spot

I checked the available interpolation method in scipy, but could not get the proper solution for my case. assume i have 100 points whose coordinates are random, e.g., their x and

Solution 1:

Use scipy.interpolate.griddata. It does the exact thing you need

# griddata expects an ndarray for the interpolant coordinates
interpolants = numpy.array([xnew, ynew])

# defaults to linear interpolation
znew = scipy.interpolate.griddata((x, y), z, interpolants)
