            s=input ('would you like to see the game stastics 1,yes 2,no:')
            
            switch s
                
                case 1
                    num_player = 20;
WLT = zeros(num_player,3);

%...
if have_a_winner
    WLT(winner_index,1) = WLT(winner_index,1) + 1;
    WLT(loser_index,2)  = WLT(loser_index,2) + 1;
else
    WLT(player1_index,3) = WLT(player1_index,3) + 1;
    WLT(player2_index,3) = WLT(player2_index,3) + 1;
end
                    %disp('stastics')
                    
                case 2
                    if s== 2
                        disp('main menu')
                        
                        playon=false;
                   
                 
                        
                    end

Put the whole thing inside a while loop, and when you want to go back to the beginning call continue.
