Using a Value (Vanilla) Class When using a value class you need to tell Matlab to store a modified copy of the object to save the changes in the property value. So, >> a=testprop >> a.Request(5); % will NOT change the value of a.numRequests. 5 >> a.Request(5) 5 >> a.numRequests ans = 0 >> a=a.Request; … Read more
Matlab has constants now. The newer (R2008a+) “classdef” style of Matlab OOP lets you define constant class properties. This is probably the best option if you don’t require back-compatibility to old Matlabs. (Or, conversely, is a good reason to abandon back-compatibility.) Define them in a class. classdef MyConstants properties (Constant = true) SECONDS_PER_HOUR = 60*60; … Read more
Starting from R2010b, MATLAB supports enumerations. Example from the documentation: classdef Colors properties R = 0; G = 0; B = 0; end methods function c = Colors(r, g, b) c.R = r; c.G = g; c.B = b; end end enumeration Red (1, 0, 0) Green (0, 1, 0) Blue (0, 0, 1) end … Read more
I’ve been working with OO MATLAB for a while, and ended up looking at similar performance issues. The short answer is: yes, MATLAB’s OOP is kind of slow. There is substantial method call overhead, higher than mainstream OO languages, and there’s not much you can do about it. Part of the reason may be that … Read more
