Get the time of the messages

Hi, I've got a code that gives me the messages that repeat from two different strings. What I want is to get the time from the those messages but when I do it I get an error. Here is the code:

for K = 1:1:N
   all_match_AIS = find(msg_AIS1(K) == msg_AIS2); % encontrar mensajes iguales
   if isempty(all_match_AIS) %fprintf para escribir datos en un archivo de texto
%        fprintf('No hay coincidencias para la linia #%d -> "%s"\n', origi_AIS1(K), msg_AIS1(K)); % '%s' para un string
       continue;
   end
%    fprintf('potencial coincidencia #%d -> "%s", checking times\n', origi_AIS1(K), msg_AIS1(K));
%    disp(K), disp(all_match_AIS)
   if H1(K)== H2(all_match_AIS)
   % crear rango de coincidencia de minutos
      complete_match_AIS = all_match_AIS(M1(K) == M2(all_match_AIS) | M1(K) == M2(all_match_AIS) - 1 | M1(K) == M2(all_match_AIS) + 1);% Rango creado +-1 minuto de cada mensaje
      msg_match{K} = msg_AIS1(complete_match_AIS);
      Time_Matching = Time_AIS1(msg_match(K)) % HERE I GOT THE PROBLEM IMPORTANTE
   end 
 if isempty(complete_match_AIS)
%         fprintf('line %#d -> "%s" coincide texto pero no tiempo\n', origi_AIS1(K), msg_AIS1(K));
     else
%        fprintf ('line %#d -> "%s" coincide tambien el tiempo. Los resultados son:\n', origi_AIS1(K), msg_AIS1(K));
        msg_AIS2(complete_match_AIS) %IMPORTANTE
       
 end

end

The problem I got is the next one:

Unable to use a value of type cell as an index.

Error in matlab.internal.datatypes.parenReference_1D (line 12)
    data = data(rowIndices);

Error in duration/parenReference (line 19)
        obj.millis = parenReference_1D(obj.millis, rowIndices);

Error in CodiVicens (line 41)
      Time_Matching = Time_AIS1(msg_match(K))%coger los mensajes de las lineas que han coincidido. IMPORTANTE

Thank you in advance

Try:

Time_Matching = Time_AIS1(msg_match{K})   % curly braces

hey I get this problem:

Unable to use a value of type string as an index.

I do not why but the variable Time_AIS1 is a duration variable, I do not know if it has to be something about it

The error mesage, that the contents of msg_match{K} is a string. Then you cannot use it for indexing.
