[Discuss-gnuradio] Any Octave/Matlab folks on the list?

[Marcus Leech]

I have some X,Y,Z data that I want to turn into a gray or colour mapped 
contour plot.

The data aren't necessarily gridded, so I need interpolation.

I'm  a newbie to Octave/Matlab, and could use a hint.

I've played with contourf(), which I can make work for functions, but I 
need to load external data that is
 organized as columns of X,Y,Z in ascii.
