matlab code for filter

[frederic manseau]

Hi,

 

I found this Matlab code for filtering data which is supposed to do a Local
regression using weighted linear least squares and a 1st degree polynomial
model.

 

pethsmooth=smooth(x,50,'rloess');%%%%%%this uses a Matlab function 'rloess'
to smooth the data based on how ever number of points you want

belowzero=pethsmooth<0;%%%%%% this detects points below zero (you can't have
a negative firing rate)

pethsmooth(belowzero)=0; %%%%this sets all those <0 points to 0 in the
smoothed PETH

 

Would anyone know if it's possible to adapt this so that it can be used in
Octave?

 

 

Thank you for your help,

 

Frederic Manseau
