Details:

I was working for my program, the program is using kernel ridge regression, so
I compute matrix K as kernel matrix the add it with cI, resulting matrix
BRACKETS

BRACKETS=K+cI

(I=identity matrix and c>0)

when I try to inversing the BRACKETS, my OCTAVE 3.6.2 crashed, it said illegal
operation or something, I use command inv(BRACKETS)

when I try at MATLAB, it works fine, so it's disturbing me now because it's
part of my final graduation project.

please help me, thank you very much

ps: pardon for my bad English and I'm sorry if this topic maybe had been
solved before (didn't find the same thing like me in bug tracker)
