This example shows one way to plot 3D surfaces. The main commands are mesh(x,y,z) and surf(z,y,z) ![]() ![]() Calculate z for the surface, using component-wise computations.Create a "grid" in the xy-plane for the domain using the command meshgrid.Establish the domain by creating vectors for x and y (using linspace, etc.).It is up to you to experiment and look up these commands to better understand them. I do not explain every command or show everything. ![]() This page will not show all of them it will show the way that is the most customizable and can be easily extended to more complicated settings (like parametric equations, 3D, etc.) This is also a learn-by-example page. There are several ways to produce graphs of functions. There are many other examples on the H-drive! You may want to have the following commands at the top of your script files to "start fresh" clc % clears the command windowįormat % resets the format to the default format
