plot a 3d circle surface
in [Matlab]
|
From: jiuwenzh on 23 Feb 2010 15:06 I am trying to figure out a way to plot a 3d surface in matlab. There are lots of data x and y,z is indepentent of x and y. I only want to plot a circle surface with the conditions: x^2+y^2<=25 but I awalys get a rectangular surface. I tried using loop to delete the data x^2+y^2>25, but the resuts looks ugly. How should I solve this problem? Thanks in advance.
