How can I write "words" and time format in a matrix ?

I have this code

m=0.5
A = poissrnd(m, 24, 1);
for i=1:24;
  if A(i,:)== 0;
     DT(i,:)= 00:00:00;               % I want it to be on time format, 00:00:00 How??
  elseif 10>=A(i,:)>0;
      DT(i,:)= 00:00:10;              % I want it to be on time format , 00:00:10  
  else A(i,:)>10;
      DT(i,:)=00:00:20;               % I want it to be on time format, 00:00:20 

    end
end

As I write on the code how can I make the code to write time format?

Thank you you very much

It depends on what you want DT to be. A datetime vector?

What does this mean:

 As I write on the code how can I make the code to type ' no delay'
 and write time format?

It was a mistake. I edit the question and I forget to delete it.

sec = zeros(size(A));
sec(0 < A & A <= 10) = 10;
sec(A > 10)          = 20;
DT = datetime(0, 0, 0, 0, 0, sec, 'Format', 'HH:mm:ss');

Note:

elseif 10 >= A(i,:) > 0

This will not do, what you expect. Matlab evaluates this from left to right. In the first step 10 >= A(i, :) replies a logical vector, which contains TRUE or FALSE. Then TRUE > 0 or FALSE > 0 is calculated. You mean:

elseif 10 >= A(i,:) && A(i, :) > 0

Thank you I will try it. and I will get back :)

It is not possible to put strings or datetime items into a numeric array.

You can construct cell arrays, or you can construct table objects.
