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 <=`

with 500 points.`t`<= 2*piIf

`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 first argument

`hax`is an axes handle, then plot into this axis, 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 <=`

with 60 points in each dimension.`x`|`y`<= 2*piIf three functions are passed, then plot the parametrically defined function

`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 axis, 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);
