Hi

Does anyone know:

Which interpolation method is better for a non uniform data grid with
complex numbers and Why?

Thanks

Please learn how to post messages... asking 4 times won't get 4 times

Why do you want to know? Homework?

First, interpolation of complex numbers:

Then, interpolation on a nonuniform grid should be easy enough .. I think.
