I have unstructured [x y z] data from CFD calculations, and would like to convert them to a rectangular meshed grid. - is that possible?

I'm thinking of something like

N = 50; M = 5;
x = rand(1,N);
y = rand(1,N);
z = rand(1,N);

[Xi Yi] = meshgrid(linspace(0,1,M));
Zi = interpUNSTRUCTURED(x,y,z,Xi,Yi)

regards,
anders

griddata is a place to start. Or download gridfit from
the FEX to give a smoother surface directly.
