Right, Julien. I'm really only interested in Octave; I'm a card carrying member 
of the Free Software Foundation.

Be that as it may, here is a script that should run in MatLab. I would be very 
interested in the MatLab result.

Also, for your curiosity, I've uploaded a picture of the 2014 performance of
   SPY  - SPDR S&P 500 (the largest and oldest exchange traded fund)
   BND  - Vanguard Total Bond Market ETF (the largest bond ETF)
   VIC  - An unattended ETF portfolio in BND, XLP, XLV, and XLU
   X156 - An unattended portfolio of 6 ETFs that gained exactly 15% in 2014
The X156 portfolio  performed very much like the efficient p15 in the 
matlabtest. It was much, much less volatile than SPY, but it earned a bit more. 
(SPY earned 13.5% in 2014.)

Thanks for your continuing comments and help!
