I need to remove randi from the for loop. Any help would appreciate.

     I=30;
     t1=randi([1 5],1,I);
     t2=randi([6 10],1,I);
    for i=1:I   
    TD(1,i)=randi([t1(1,i) t2(1,i)],1,1);
    end

That seems easy enough to do, although it would be interesting to know the reason you want to do it.

It would be best leave your code as it is, and simply overwrite ‘TD’ with something else.

I don't want in the loop values be random again. If by overwrite you mean B = TD, again the values in the loop created randomly. I need the size of TD be (1,I), and TD should be values within t1 and t2.

randi() takes a range of integers. Since you want that range to change every column, I don't see how there is a way to do it without a for loop. However, if the (badly-named) I is less than a million, the for loop will be fast (less than a second or so)
