https://www.mathworks.com/help/matlab/ref/fimplicit.html is recommended these days.
ezplot(@(x,y)x.^2 - 9*y.^2 - 81)

The ezsurf (and fsurf) functions accept only single-variable functions.
Try this:
figure
ezcontour(@(x,y) x^2 - 9*y^2 - 81, [-10 10 -10 10])
the fcontour, ezsurf and fsurf functions are also options.
Make appropriate changes to get the result you want.

Another possibility:
figure
hec = ezcontour(@(x,y) x^2 - 9*y^2, [-50 50 -50 50]);
hec.LevelList = 81;
.
