I am sharing one example here, hope it helps

data=randi(3,[1,10]);
data_cell=table(data);
str_data={'Normal','Left','Right'};
% Just kee those strings as per number accordingly
str_name=cell(1,10);
for i=1:length(data)
    str_name(i)=str_data(data(i));
end 
T=table(data',table(str_name'))

Result:

T =
  10×2 table
    Var1       Var2   
               Var1   
    ___    __________
     1      {'Normal'}
     3      {'Right' }
     3      {'Right' }
     3      {'Right' }
     1      {'Normal'}
     3      {'Right' }
     2      {'Left'  }
     2      {'Left'  }
     2      {'Left'  }
     3      {'Right' }

thank you but i have problem my matrix name is ANNOTD have the number i wil replace and can but number 0 to replace

i write this to take number but is not work data=ANNOTD(3,[1,10]);

Did you read the documentation for the randi function? This was just to create some example data to show working code. You should replace it with your own data.

Did you do a basic Matlab tutorial? You may consider doing the Onramp tutorial (which is provided for free by Mathworks).

%create some sample data for illustration purposes
%comment this next line out for your actual use
ANNOTD = randi([0 3],[10, 1]);

%now that we have the data, do the work

heart = table(ANNOTD);
names = {'Gummi', 'Normal','Left','Right'};
heart.Word = categorical(heart.ANNOTD, 0:length(names)-1, names)

heart = 10x2 table
    ANNOTD     Word 
    ______    ______

      3       Right 
      0       Gummi 
      1       Normal
      1       Normal
      2       Left  
      3       Right 
      0       Gummi 
      2       Left  
      3       Right 
      1       Normal

thank you so much it is work
