Plot a parametrically defined curve in three dimensions.
FX, FY, and FZ are strings, inline functions, or function handles
with one argument defining the function. By default the plot is
over the domain ‘0 <= T <= 2*pi’ with 500 points.
If DOM is a two element vector, it represents the minimum and
maximum values of T.
N is a scalar defining the number of points to use in plotting the
function.
If the "animate" option is given then the plotting is animated in
the style of ‘comet3’.
If the first argument HAX is an axes handle, then plot into this
axes, rather than the current axes returned by ‘gca’.
The optional return value H is a graphics handle to the created
plot.
fx = @(t) cos (t);
fy = @(t) sin (t);
fz = @(t) t;
ezplot3 (fx, fy, fz, [0, 10*pi], 100);

Plot the mesh defined by a function.
F is a string, inline function, or function handle with two
arguments defining the function. By default the plot is over the
meshed domain ‘-2*pi <= X | Y <= 2*pi’ with 60 points in each
dimension.
If three functions are passed, then plot the parametrically defined
function ‘[FX(S, T), FY(S, T), FZ(S, T)]’.
If DOM is a two element vector, it represents the minimum and
maximum values of both X and Y. If DOM is a four element vector,
then the minimum and maximum values are ‘[xmin xmax ymin ymax]’.
N is a scalar defining the number of points to use in each
dimension.
If the argument "circ" is given, then the function is plotted over
a disk centered on the middle of the domain DOM.
If the first argument HAX is an axes handle, then plot into this
axes, rather than the current axes returned by ‘gca’.
The optional return value H is a graphics handle to the created
surface object.
Example 1: 2-argument function
f = @(x,y) sqrt (abs (x .* y)) ./ (1 + x.^2 + y.^2);
ezmesh (f, [-3, 3]);
Example 2: parametrically defined function
fx = @(s,t) cos (s) .* cos (t);
fy = @(s,t) sin (s) .* cos (t);
fz = @(s,t) sin (t);
ezmesh (fx, fy, fz, [-pi, pi, -pi/2, pi/2], 20);

Plot the mesh and contour lines defined by a function.
F is a string, inline function, or function handle with two
arguments defining the function. By default the plot is over the
meshed domain ‘-2*pi <= X | Y <= 2*pi’ with 60 points in each
dimension.
If three functions are passed, then plot the parametrically defined

a disk centered on the middle of the domain DOM.
If the first argument HAX is an axes handle, then plot into this
axes, rather than the current axes returned by ‘gca’.
The optional return value H is a 2-element vector with a graphics
handle for the created mesh plot and a second handle for the
created contour plot.
Example: 2-argument function
f = @(x,y) sqrt (abs (x .* y)) ./ (1 + x.^2 + y.^2);
