surface extrapolation

[moore]

I am trying to extrapolate data on a surface. THe existing data points I have are good but a whole corner of the plot is missing due to missing data. I want to plot the data and obtain extrapolation for the missing corner. Can you help?

Hi,
The real answer is lay in the spline toolbox.
If you don't have it try interp2, may be it works also for extrapolation.
If not try to use spline for each row and each column and take the average.
