I have a large xy plane of data with ~26000 points. The points are not in a
rectangular grid.
I would like to interpolate to a new point within this dataset. Is there an
easy way to do this?
I have tried interp2d, but it does not give me a valid result, e.g.
from scipy.interpolate import interp2d
in2=interp2d(R,Z,volt)
in2(R[0],Z[0]) = [ 0.310331]
whereas
volt[0]=1.0
And I get this warning:
Warning: No more knots can be added because the additional knot would
coincide
with an old one. Probably cause: s too small or too large a weight
to an inaccurate data point. (fp>s)
kx,ky=1,1 nx,ny=4,282 m=26328 fp=1195.252616 s=0.000000
