MATLAB: How can share the handles variable between two skripts

MATLABmatlab gui

My question ist:
1) i have created a panel with text in a skript
str_velocity = "%.2f km/h";
vxvRef= 0;
handles.str_velocity = sprintf(str_velocity, vxvRef);
if ~isempty(vxvRef)
uicontrol(handles.vehicleData, 'Style','text','Position', [148 -12 87 100], 'String',handles.str_velocity,'FontSize',11);
end
2) In another skript i have:
vxvRef= 3;
% try to acces the handles.str_velocity and update the new vxvRef into handles.str_velocity to show this in the panel
set(handles.vehicleData,'String',vxRef)
it showed me an error. How can I share the handles variable between two skripts and is my approach right ? Thanks

If they are scripts, they should be created as methods of a class which is abstracted from handle superclass. 
classdef MyClass < handle
    properties
        prop1
        prop2
        prop3
    end
    methods 
        function obj = MyClass
            obj.prop1 = uicontrol (.. 'Style','text',..);
            obj.prop2 = uicontrol (..'Style','pushbutton','Callback',@obj.ButtonPushedCallback);
            obj.prop3 = 500 % some velocity or other values 
        end
    
        function textChange(obj,source,event)
            % obj is MyClass object

            % source is text object
            % event is the event indicates any action taken
            obj.prop1.String = 'NewString';
            % You can also change text element string with using source object
            % source.String = 'NewString';
        end
    
        function ButtonPushedCallback(obj,source,event)
            % obj is MyClass object
            % source is pushbutton object
            % event is the event indicates that button pressed
            obj.textChange; % calls the text change function above
        end
    end
end
% You can reach all properties in all methods defined in this class with obj.property notation.
