I have a time range (t) going from 1 to 20, and a random collection of data of 20 points (y). I need to have y(1,:) for t(1,:), y(2,:) for t(2,:) and so on. This is what I wrote:

`for t=1:1:20.0 a = y(1,:) : y(20,:)end`

But all this executes is the just one value of y (the first or the last, I can't tell because they are the same number). What should I correct?
