====== Math 445 Lab 10: 2D and 3D graphics ====== Important matlab commands: **linspace, meshgrid, pcolor, surf, contour, surfc, contourf, quiver, mesh, load, subplot, pcolor, shading**. ===== Part A: pcolor, meshgrid, shading, subplot ===== Skim the Matlab documentation for ''linspace, meshgrid,'' and ''pcolor''. Create a 2D mesh from −π to π with 30 points in both the //x// and //y// directions. Then for each position in the mesh let //z = cos(x) sin(y)//. Use ''pcolor,'' ''axis equal,'' and ''axis tight'' to generate this figure: {{ :gibson:teaching:fall-2012:math445:a.png?nolink&500 |}} But don't you hate those ugly black lines? You can get rid of them with the ''shading'' command. Use ''subplot'' and the ''shading'' command to generate this plot: {{ :gibson:teaching:fall-2012:math445:lab10-fig2.png?nolink&500 |}} Attribution: based on Prof. Mark Lyon's "Advanced Graphics" lab for Math 445, which was adapted from an [[http://yapso.sourceforge.net/demo/demo.html | Octave demo]].
