plot parametric surface in matlab

To plot a parametric surface in MATLAB, we can use the fsurf function. This function plots a surface defined by the parametric equations x = f(u,v), y = g(u,v), and z = h(u,v).

Here is the basic syntax for using fsurf to plot a parametric surface:

main.m
fsurf(xfunc, yfunc, zfunc, [umin, umax, vmin, vmax])
53 chars
2 lines

where xfunc, yfunc, and zfunc are function handles that define the parametric equations, and [umin, umax, vmin, vmax] are the ranges for the parameters u and v.

Here is an example of how to use fsurf to plot a parametric surface:

main.m
% Define the parametric equations
x = @(u,v) sin(u) .* cos(v);
y = @(u,v) sin(u) .* sin(v);
z = @(u,v) cos(u);

% Define the parameter ranges
umin = 0;
umax = pi;
vmin = 0;
vmax = 2*pi;

% Plot the surface
fsurf(x, y, z, [umin, umax, vmin, vmax]);

14 lines

This will plot a parametric surface of a sphere. You can modify the parametric equations to plot other surfaces.
