Re: interp2 partial derivatives

Hi John,

I want to use method 'spline' or 'bicubic'. I think there should be an alternative to using 'gradient', because one uses piecewise polynomials in both methods.

Which method? They are all zero for nearest neighbor
interpolation. All are piecewise constant for the linear
method. So the derivatives will depend on the method
you choose.

The simplest solution is to use gradient.
