How to write a parallel computing script for this situation?

I have a program that has been running for more than a week. I have no idea how many additional days it will take. Would anyone please help me write a parallel computing script for it?
It is as simple as this:
z = f(x, y)
The thing is that my x and y have a size of 40 million (row) x 1 (column). Normally, it would be much faster to run them together as column variables, instead of going through them one row at a time.
What would my parfor loop look like?
Many thanks!

There is a strong chance that your code is simply written poorly, that a parallel computing solution is the wrong approach. But that is impossible to know. You would be best served by spending the time to lean to use the profiler tool, to see whereyour code is slow. And to learn ways to improve your code. But this question is not a question about MATLAB, just a bulletin board request, asking for somoen to provide code and general tutoring on how to use a toolbox, without knowing anything about your real problem, or even if it would help.
