My for loop execution is not working.

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?

Your question is not clear

[Hiskiel Stephanus]

I am assuming you are trying to assign values to an "a" matrix. Try making "a" a dynamic array by saying

a(1,t) = y(1,:) : y(20,:)

Answer 1

for t = 1:20
  a = y(t,:);
  fprintf('y value #%t was %g\n', t, a);   %example of using the data
end

Hm, thank you very much. This works well for me.

PS: If I happen to use a part of this code in my summer project, I would credit you. :p Hehe.
