NaN and Surf function

[Kyle Snow]

My question is regarding the handling of NaN values for the Z-coordinate in the function

 

surf(x,y,Z).

 

These values exist because my gridded data set has an irregular boundary. The surf command does not seem to handle this well. In matlab, these data points are simply not plotted, and the surf plot for the non-NaN points looks fine. Is there a way I can get this to work using Octave’s surf function?

 

Note that I am running WindowsXp, and I downloaded the exe file from

http://superb-east.dl.sourceforge.net/sourceforge/octave/octave-2.1.73-1-inst.exe.

I have not obtained the Octave source code.

 

Thanks,

 

Kyle
