I've created a MATLAB class, something like: classdef myclass properties x_array = []; end methods function increment(obj,value) obj.x_array = [obj.x_array ; value); end end end The problem is, the property x_array is never modified when I invoke the increment() function: ex: >>s = myclass >>increment(s,5) >>s.x_array ans = [] I did some research, and I reached a conclusion that this is because of MATLAB using Lazy Copy for objects, making my class inherit the HANDLE class should have solved this, but it didn't, does anybody know why this is happening? And if extending the handle class is

I am trying to create a MATLAB class with a member variable that's being updated as a result of a method invocation, but when I try to change the property within the class it (apperently, from what I understood from MATLAB's memory management) creates a copy of the object and then modifies it, leaving the original object's property untouched. classdef testprop properties numRequests=0; end methods function Request(this, val) disp(val); this.numRequests=this.numRequests+1; end end end . >> a=testprop; >> a.Request(9); >> a.Request(5); >> a.numRequests ans = 0 Azim Using a Vanilla Class When

Is there a way to define static member variables in MATLAB classes? This doesn't work: classdef A properties ( Static ) m = 0; end end It suggests to use keyword "Constant" instead of "Static", the constant properties cannot be modified. I want a variable common to all objects of class A and I want to be able to modify that variable in methods of class A . So what I need is a private static member variable. Is there a way to obtain it in MATLAB? Found out that a workaround can be done using persistent variables in static member functions. In this case you should inherit all your classes from a

Are there enumerated types in MATLAB? If not, what are the alternatives? Marc You can get some of the functionality with new-style MATLAB classes: classdef (Sealed) Colors properties (Constant) RED = 1; GREEN = 2; BLUE = 3; end methods (Access = private) % private so that you cant instantiate function out = Colors end end end This isn't really a type, but since MATLAB is loosely typed, if you use integers, you can do things that approximate it: line1 = Colors.RED; ... if Colors.BLUE == line1 end In this case, MATLAB "enums" are close to C-style enums - substitute syntax for integers. With the
