My remarks:
- add more details about input / output arguemnts
- Add better description about the submission (who may use it, for what)
- add error checking
- add examples scripts
Also, I've tried to run it with:
xinf=randn(100,1);
np=1;
nq=1;
[sigma,outn,outd]=arma_last(xinf,np,nq);
And all I got was 1 in all the outputs. I know what a ARMA model is. Something's got to be wrong.
I'll be glad to give a better rating if the improvements are made..
