Because Octave's builtin functions you are able to compile octave with
GCC profiling option ("-pg") and using gprof to postprocess. This would
give you a hint in which part of functions CPU power is gone.

With this kind of information it could be possible to rewrite such a
function in a more general way.

Additionally you could time your functions by using tic/toc and write
results in an external file.

Bye Andreas
