Hi,

I am trying to smooth the edges of this surface plot: http://oi55.tinypic.com/118evrm.jpg

The blank regions are set with NaN placeholders, but this results in a zigzag edge. I've tried implementing interp2, griddata, and gridfit, but I haven't been able to use them to account for NaN's in the data set.

I searched the forums and saw some ideas, but again nothing in particular to rough edges caused by NaN's.

Any suggestions/references?

Much appreciated! Hussain

Possibly John's inpaint_nans contribution would be useful for your purpose ?

Thanks for the response; I actually came up with a problem specific solution by evaluating the solution further away from places where those spikes occur.
