MATLAB: How can i call class from a function

Question

Hello,

i have a class with private properties and public methods to change the properties.

I want to call the methods of the class from a function in another m.File and change the methods.

At the end a function display should return a value. Something like this:

value=dispspeed(classcar);

value=10;

How can it be done?

Thank you in advance!

You should really have a look at the documentation of how you write classes in Matlab, starting for example here.

With the code below in a file called 'car.m', you can call aCar=car(3);aCar.showSpeed and it will disp the speed.

classdef car
    properties
        speed
    end
    methods
        function obj = car(set_speed)
            if nargin>0
                obj.speed=set_speed;
            else
                obj.speed=0;
            end
        end
        function obj = setSpeed(obj,set_speed)
            obj.speed=set_speed;
        end
        function showSpeed(obj)
            disp(obj.speed)
        end
    end
end
