Class Code

Here is a simple class definition with one property and a constructor method that sets the

value of the property when there is an input argument supplied.

classdef MyClass

properties

Prop

end

methods

function obj = MyClass(val)

if nargin > 0

obj.Prop = val;

end

end

end

end

To create an object of MyClass, save the class definition in a .m file having the same

name as the class and call the constructor with any necessary arguments:

d = datestr(now);

o = MyClass(d);
