Storing Values From a Loop

I'm doing a project involving an implementation of Euler's method for class, and am using a "for" loop to increment my values. The code below runs, but whatever new y value I get is overwritten as the loop goes through. I need to be able to save those y values after each time through the loop and put them into a matrix so that they can later be graphed. I'm not sure how to do this, so any help is appreciated!

 a=1250
 q=500
 c=160
 n=0.5
 y=1.1
 for t=0:n:2
    s=3*(q/a)*sin(t)^2-(c*(1+y)^1.5)/a
    y=y+s
 end

Thanks,

-Kyle

Replace

    s=3*(q/a)*sin(t)^2-(c*(1+y)^1.5)/a
    y=y+s

with

    s=3*(q/a)*sin(t)^2-(c*(1+y(end))^1.5)/a;
    y=[y y(end)+s];

That's awesome, thanks! How does the (end) thing work? I assume it's a sort of function since the "s=" equation is still starting y at 1. 1

end is a keyword, not a function. It simply picks out the last element of an array. For example, if x = [1 2 3 4 5], then x(end) = 5
