Re: zeros(n)

>From the help file for zeros:

If invoked with a single scalar integer argument, return a square NxN matrix.

So, if you call the function as:
zeros(20000)
You're requesting a matrix of size 20000x20000

In your for loop, you're initializing a 1x20000 array.  If you want
zeros to do what your for loop is doing, you should call it as:
zeros(1, 20000)

Hope this helps.
