Subject: assign a number to a string

Dear all,

I have a list of string:

txt={'BBB3', 'BBB2', 'BBB1', 'A3', 'A2', 'A1','AA3','AA2','AA1'};

i would like to assign a value to each string. For instance,
 

Here is my code
for i=1:length(txt)
           if isequal(txt{'i'},'BBB3')

             txt{'i'}=11;
   
           elseif isequal(txt{'i'},'BBB2')

            txt{'i'}=12; 

            elseif isequal(txt{'i'},'BBB1')
            txt{'i'}=13;    

             elseif isequal(txt{'i'},'A3')

                 txt{'i'}=14;
                 
           elseif isequal(txt{'i'},'A2')
               txt{'i'}=15;
           elseif isequal(txt{'i'},'A1')
                    txt{'i'}=16;
             elseif isequal(txt{'i'},'AA3')
                 txt{'i'}=17;
             elseif isequal(txt{'i'},'AA2')
                 txt{'i'}=18;
            else
               txt{'i'}=20;
           end 
            
         end

Basically the output I am looking for is:

txt={11, 12, 13, 14, 15, 16, 17, 18 ,19};

however when I run the code and type txt in the screen in order to retrieve the final output  i still get the initial input  which is txt={'BBB3', 'BBB2', 'BBB1', 'A3', 'A2', 'A1','AA3','AA2','AA1'};

I might have missed something somewhere. ANy help is much appreciated  Thanks
