MATLAB® provides many techniques for plotting numerical data. Symbolic Math Toolbox™ expands these graphical capabilities by providing plotting functions for symbolic expressions, equations, and functions. These plots can be in 2-D or 3-D as lines, contours, surfaces, or meshes. You can create plots in Cartesian or polar coordinates. You also can create animated plots.
Plot symbolic expressions, including parametric or implicit expressions, in 2-D or 3-D as line, contour, or surface plots.
Plotting in spherical coordinate system.
Find tangent plane and normal line of implicitly defined surface.
