3d plot of a function with two variables
Hi, I am having a problem with increasing the resolution of my 3-d plot. I have pasted the code below. If I try to increase the mesh density, then Av and delta also need to increase, but they can't increase in the for loop for some reason. Please help close all clear all x=[1:15]; y=[1:15]; [X,Y] = meshgrid(x... 7 Jun 2010 16:35
