I am writing a simple MATLAB class that has a few properties and a method. The constructor of the class initializes the properties with the default values. The method of the cla

Answer 1

Your class needs to inherit from the handle superclass. Try:

classdef classTest < handle
properties
    p1
    p2
    p3
    p4
end

methods

    function obj = classTest()
        obj.p1 = 0;
        obj.p2 = 0;
        obj.p3 = [];
        obj.p4 = '';
    end

    function obj = updateSomeProperties( obj, p1 )
        obj.p1 = p1;
    end
end
end 

This will give,

>> b = classTest

b = 

classTest with properties:

p1: 0
p2: 0
p3: []
p4: ''

>> b.updateSomeProperties(10)

ans = 

  classTest with properties:

p1: 10
p2: 0
p3: []
p4: ''

>> b

b = 

classTest with properties:

p1: 10
p2: 0
p3: []
p4: ''
