![]() ![]() I think this solution is much nicer than using persistent variables in functions, since you can reuse the StaticVarContainer as often as you want, it's easier to use, and furthermore, you directly see the initialisation of the static variables in the properties section. You'll see, that classvars is indeed shared. If you run this sample code obj1 = ClassWithStaticMembers(3) I've added a sample implementation that shows how that can be used: classdef ClassWithStaticMembersĬlassvars = StaticVarContainer('foo', 0, 'bar', 2) Ĭlassdef StaticVarContainer < dynamicpropsįunction obj=StaticVarContainer(varargin) Then some_function is invoked only once, and if it returns an object of class type, this will be shared by all instances. That means, if you have a definition like classdef foo Methods (Access = private, Static = true)Īnother workaround to get something like static properties is to use the fact that initialisation code for member variables is only executed once when the class file is loaded. Note that this is not a handle class (though it would work perfectly well on a handle class as well). This approach works just as well for private static properties like you requested, but the demo code is a little longer. So, for instance, this is the expected output from a test of this functionality: > StaticVarClass.staticVar and be set via: StaticVarClass.staticVar(newval) Now the static property staticVar can be read via: StaticVarClass.staticVar ![]() The only difference between this implementation and a hypothetical (but impossible see Mikhail's answer) true static property is the syntax for setting the member variable. Here's a direct way to create a static property in Matlab. ![]() = C" will introduce a new variable A that is a struct array containing a You should use a persistent variable (technique from the MATLAB as 1980 applied in year 2011)!įor completeness I should mention that actually there is as of 2010b an undocumented and probably not longer supported static property modifier.įor background see here the answer of Dave Foti, MATLAB OO group manager: ![]()
