Listing Class Methods

The function call

methods('class_name')

or its command form

methods class_name

shows all the methods available for a particular class. For the polynom example, the output is

methods polynom
Methods for class polynom:

char	display	minus	plot	polynom	roots
diff	double	mtimes	plus	polyval	subsref

Plotting the two polynom objects x and p calls most of these methods.

x = polynom([1 0]);
p = polynom([1 0 -2 -5]);
plot(diff(p*p + 10*p + 20*x) - 20)
