How can I extract the logical value in a loop (various columns)?

Hello, I'm runnning my code and my logical value is running, what I would like to do is exctract the logical value for several columns (from column 5 to 10) can I do it in a loop or I have to name various variables and then join them?

  idx=logical(idx);
  [X,Y]= meshgrid(T2.length,T.length);
  C = X(idx);
  D = Y(idx); 
  delta = (C - D);
  
  t = table(D,C,delta);

T2 and T are the table were I'm talking the values lenght is in the 5th column and I would like to do the same for column 6,7,8,9,10 is it possible without naming them again? and then do the substraction?

have a nice Friyay

is this what you are looking for?

idx=logical(idx);
for i = 5:10  
[X,Y]= meshgrid(T2.(i),T.(i));
  C = X(idx);
  D = Y(idx); 
  delta = (C - D);
  
  T(i-4).table = table(D,C,delta);
end

yes, thank you for your answer

hello, it's me again, sorry but I wanted to join all of them in a single table, I have an structure and when I tried to combine I could not because they have the same name variable, I name them one bye bye but is it a shorter way to do it?

thank you

  [X,Y]= meshgrid(T2.length,T.length);
  C1 = X(idx);
  D1 = Y(idx); 
  delta1 = (C1 - D1);
  
  [X,Y]= meshgrid(T2.wmax,T.wmax);
  C2 = X(idx);
  D2 = Y(idx); 
  delta2 = (C2 - D2);
  
  [X,Y]= meshgrid(T2.wmin,T.wmin);
  C3 = X(idx);
  D3 = Y(idx); 
  delta3 = (C3 - D3);
  
  [X,Y]= meshgrid(T2.wav,T.wav);
  C4 = X(idx);
  D4 = Y(idx); 
  delta4 = (C4 - D4); 
  
  [X,Y]= meshgrid(T2.angle,T.angle);
  C5 = X(idx);
  D5 = Y(idx); 
  delta5 = (C5 - D5); 
  
  t = table(D1,C1,delta1,D2,C2,delta2,D3,C3,delta3,D4,C4,delta4,D5,C5,delta5);

NewTable = []
for i =1:5
M = table2array(T(i).table)  %table(D,C,delta);
NewTable = [NewTable M]
end

FinalTable = array2table(NewTable,"VariableNames",["D1","C1","delta1","D2","C2","delta2","D3","C3","delta3","D4","C4","delta4","D5","C5","delta5"]);

or

idx=logical(idx);
M = [];
for i = 5:10  
[X,Y]= meshgrid(T2.(i),T.(i));
  C = X(idx);
  D = Y(idx); 
  delta = (C - D);
  M = [M D,C,delta]
end

t = array2table(M,"VariableNames",["D1","C1","delta1","D2","C2","delta2","D3","C3","delta3","D4","C4","delta4","D5","C5","delta5"]);

You can also generate a string of variable names, which you can automate as well if you just want to add numbers to them.
