Improving resolution for a surf plot in MATLAB

I am using the SURF command to represent some data. I want to plot the surface of a disc in a 3d chart.
The only problem is that my data is in a 9x9 format, this naturally results in a square looking surface. I’d like for the resulting surface to look like a circle.
Is there way to “cut off” the edges somehow?

Hi, I moved your answer to a comment on Doug's answer. That's a good place for that sort of back and forth.

Interpolate to refine your mesh.

NaN does not get shown in a surf plot.
a = magic(10)
a([1,2,11,90,99,100]) = NaN
surf(a)

There is only so much you can do with that coarse of data. Can you sample more data?

Is it possible then to implement a smooth curve at the rough edges? I ask in a general sense when larger data sets are in question.
