change the current uitabmatlab guiuitabuitabgroup

Hello, I'm a beginner in Matlab GUI, I have a tabgroup like bellow code and a push button, I don't know how to code the callbacks in order to change tab by pressing the push button.
unction Main_TabbedTest
clc; clear; close all;
%% Base figure
S.fig = figure('NumberTitle','off', 'Name', 'Main_TabbedTest', ...
    'MenuBar','none', 'ToolBar','none', 'Units','Norm', ...
    'Position',[.2 .2 .6 .6], 'Resize','off', 'Color',.94*[1 1 1]);
%% Tabs
S.tb = uitabgroup('unit','norm', 'pos',[0 0 1 1]);%[0 .3 1 .7]
S.tab1 = uitab('parent',S.tb, 'title',' Tab 1 ');
S.tab2 = uitab('parent',S.tb, 'title',' Tab 2 ');
FS=14;
%======== 'Pushbutton'========== 
S.Apply = uicontrol('parent',S.tab1,'style','pushbutton', 'unit','norm', ...
    'pos',[0.65 0.23 0.13 0.08],'String','Next tab','fontname','Cambria','fontsize',FS,'TooltipString','Push to aplly properties ',...
    'Callback',@buttonApply );

Hi Amir,
Try the code below. I have commented some lines.
classdef Main_TabbedTest < handle
    % you should create a handle class to pass object reference into
    % callback functions
    properties
        S % struct property to store tab, button items
    end
    
    methods
        %Constructor method
        function tabTestObj = Main_TabbedTest
            
            %% Base figure
            tabTestObj.S.fig = figure('NumberTitle','off', 'Name', 'Main_TabbedTest', ...
                'MenuBar','none', 'ToolBar','none', 'Units','Norm', ...
                'Position',[.2 .2 .6 .6], 'Resize','off', 'Color',.94*[1 1 1]);
            %% Tabs
            tabTestObj.S.tb = uitabgroup('unit','norm', 'pos',[0 0 1 1]);%[0 .3 1 .7]
            tabTestObj.S.tab1 = uitab('parent',tabTestObj.S.tb, 'title',' Tab 1 ');
            tabTestObj.S.tab2 = uitab('parent',tabTestObj.S.tb, 'title',' Tab 2 ');
            FS=14;
            %======== 'Pushbutton'==========
            
            S.Apply = uicontrol('parent',tabTestObj.S.tab1,'style','pushbutton', 'unit','norm', ...
                'pos',[0.65 0.23 0.13 0.08],'String','Next tab','fontname','Cambria','fontsize',FS,'TooltipString','Push to aplly properties ',...
                'Callback',@tabTestObj.buttonApply );
            
        end
        
        % Apply buton callback
        function buttonApply(obj, handle,evntdata)
            % obj: Main_TabbedTest object
            % handle: button object handle
            % eventdata: action data
            
            % S.tb is stored as tab group SelectedTab is a property of
            % tabgroup stores selected tab object. you can assign tab object as follows:
            
            %% OPTION 1
            set(obj.S.tb, 'SelectedTab',obj.S.tab2);
            
            %% OPTION 2  
            % if you want to do it as numeric obj.S.tb.Children includes
            % 2x1 tab objects array select the second one or first one:
            % obj.S.tb.SelectedTab = obj.S.tb.Children(2); ... comment option1 and uncomment
            % and try this           
            
        end
    end
end
