| 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 the figure on the left. 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 the figure on the right | Skim the Matlab documentation for ''linspace, meshgrid,'' and ''pcolor''.
