ISA
Definition	A function which returns true if object is a given class. ISA(OBJ,'class_name') returns true if OBJ is of the class, or inherits from the class, 'class_name' and false otherwise.
Example	function acct = BankAccount(data) if nargin == 0    acct.balance = 0;    acct = class(acct,'BankAccount'); elseif isa(data, 'BankAccount')    acct = data; else    acct.balance = data;    acct = class(acct,'BankAccount'); end   In this case if data was a class, ISA would return a true and the object acct would just be a copy of data.
