Placing the ouputs of while loop in an array

I don't necessarily have a code written, yet but I was just wondering how I could take the outputs(all iterations) of a while loop and return a vector with the outputs.

Thanks.

What is the problem. Start putting them as soon as they are generated.

if true
    index = 0 
    a(index)=output 
    index = index+1
end

I'm sorry I'm still having trouble understanding how to go about doing this. My code is as follows:

if true
  function [r,rHist,N,fRoot] = newtonRaphE7(fHan,dfHan,x0,fTol,iterMax)
  counter = 0;
  while abs(fHan(x0)) > fTol
  x0 = x0 - (fHan(x0))/(dfHan(x0))
  counter = counter + 1
  if counter > iterMax
  error(['Number of iterations exceeded the limit'])
end
end
N = counter
r = x0
end

So I would like to add the output rHist, and have it be a vector comprised of the output for all iterations of the while loop.

@Harshit: Move the "index = 0" out of the loop.

@Joe: You define a nested function, but do not show from where it is called.
