Meshing cartesian coordiantes within a circle?

I want to do a mesh with x and y .. but I only want to display the data for a circle with radius r. I don't want to use polar coordinates since the mesg becomes less dens at the edges.

Is there a way to do this, to ignore the coordiantes outside this circle?

Hi,

You can try setting the values for the co-ordinates outside the circle to NaN. May be this will help.

How do I do that for mesh matrix x and y?
