Hi everybody,
I am an absolute novice of octave, even though I have some
experience
with matlab.
Just to get the feeling of octave, I am presently translating a
simple
(but very useful to me) script, that basically sums data with a
peak
structure. In order to do this properly, I need to centre each new
spectrum on the zero, that is the peak maximum. My strategy, in
matlab, was to make a preliminary gaussian fit, whose result was
to be
confirmed through a graphical input, to get the "zero" of the
spectrum. As of now, I am trying to understand how can I make a
gaussian fit of the data in octave. Data is simply organised as a
matrix [x,y]. Is there a built function? Sorry but I can't find
anything with online help.

How did you do it in Matlab?
If the data is statistical, then I'd recommend you calculate the
median
and standard deviation and construct the gaussian distribution
from that.
By "sums data with a peak structure" do you mean you are
constructing a
histogram?
