One of the most important computing skills is knowing how to pick the
correct tool for a job.

A 16F84 has insufficient memory, no floating point, and too limited
precision to handle this task.

It's like asking how can you complete a 3000 mile trip in 6 hours using
a bicycle. The correct answer is that you put you can the bicycle on an
airplane and fly to the destination.

In this instance the pic is the bicycle. It simply isn't the correct tool
for this job.

MATLAB is your airplane. It's the right tool. Use it.

Good Luck,

BAJ
