Use the tic/toc technique to time writeDigitalPin()--you will probably 
find that it's slower than you think.

It is well known than stepping pulse train in software is not a good 
idea---you need speed AND regularity in the timing sequence, or else the 
motor will run slowly and unreliably.

As the others have said, redesign your system so that Octave calculates 
the high-level parameters like the total number of steps, and send it to 
a hardware step generator or at least a real-timish software step 
generator.
