Why does my code looks weird (solved, thanks everyone for helping)

Too many unknowns to answer the question. An example would be good.

Why does my code only capture the last letter instead of full sentence?

for i=1:length(msg)  
  [~, index] = ismember(msg(i), letter);
  if index > 0
     set(handles.text2, 'string',morse{index});     
  end  
end

You set the String to one letter. Then you do the next iteration and set the string to the next letter, overwriting the previous.

You need to accumulate the letters into something and then set that as the string after the loop

can you please give an example :) sorry i am abit new to this

[Walter Roberson]

LC = {'x', 'l', 'c', 'o', 'c', 'n', 'z'};
for K = 1 : length(LC)
   letter = LC{K};
   letters(K) = letter;
end
letters

letters = 'xlcocnz'

[Walter Roberson]

Where is your ismember()

The point of my example is that if you are looping producing one letter at a time (decoded from the morse), then you can store the letter into a vector while you are looping, and look at the accumulated values later.

sorry i am abit new thanks for being so patient

[Walter Roberson]

letters = {};
for K=1:length(msg)
   [~, index] = ismember(msg(K), LC);
   if index > 0
     letters{k} = morse{index};
   else
     letters{K} = '?';
   end
end

converted_morse_words = strjoin(letters, ' ');
set(handles.text2,'string',converted_morse_words);
