: ezcontour (f)
: ezcontour (…, dom)
: ezcontour (…, n)
: ezcontour (hax, …)
: h = ezcontour (…)

Plot the contour lines of 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 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 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.

Example: 

f = @(x,y) sqrt (abs (x .* y)) ./ (1 + x.^2 + y.^2);
ezcontour (f, [-3, 3]);

See also: contour, ezcontourf, ezplot, ezmeshc, ezsurfc.

Demonstration 1

The following code

 clf;
 colormap ("default");
 f = @(x,y) sqrt (abs (x .* y)) ./ (1 + x.^2 + y.^2);
 ezcontour (f, [-3, 3]);

Produces the following figure
