SSE optimized exponential. Your binary may not use it. A compile from source, use of MKL non-free math library, or create an oct file that makes use of them from C. Quick search will find examples.

Is there any way to optimize this function so it does work better in Octave?
Thank you very much.Nicanor García O.
