3 Graphics

R = sqrt(X.^2 + Y.^2) + e ps;

Z = sin(R)./R;

mesh(X,Y,Z,'EdgeColor','black')

By default, MATLAB colors the m esh using the current colormap. However,

this example uses a single-colored mesh by specifying the

EdgeColor surface

property. See the

surface reference page for a list of all surface properties.

You can create a mesh with see-through faces by disabling hidden line

removal:

hidden off

See the hid den reference page for more information on this option.

Example — Colored Surface Plots

A surface plot is similar to a mesh plot except that MATLAB colors the

rectangular faces of the surface. The co lo r of each face i s determined by the

values of

Z and the colormap (a colormap is an ordered list of colors). The se

statements graph the

sinc function as a surface plot, spe cify a colormap, and

add a color bar to show the mapping of data to color:
