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)
