meshc

meshc() generates a 3D rectangulated mesh as well as a contour at the base. As shown in Figure 3-15, apart from producing a 3D plot for a given function, you also get a contour plot. Note that at this time, the equation working on matrices is written as an argument of the meshc() function , thus making the program even smaller. See Listing 3-6.

1 x=linspace(−10,10,50);

2 y=linspace(−10,10,50);

3 [xx,yy]=meshgrid(x,y);

4 meshc(xx,yy,2−(xx.ˆ2+yy.ˆ2))
