Bivariate Pchip

Hi all,

I would like to use Pchip function to interpolate my 2-dimensional data set.

I'm actually using spline interpolation (with csapi function) but it doesn't work well.
I think that Pchip will be better for my data set but I have no idea how to use it with 2 variables: x1 (n values) and x2 (m values) are my variables and V=f(X1,X2) is the n*m matrix containning all values taken by f for each couple (x1,x2)

The second question can we have the result of pchip in PPFORM?

Thank you very much for you help!
