Dear All,
I have a question about FIR and orthogonalise issue.
I have read very interesting posts about ortho. of EVs but I have not found
anything about ortho of FIR functions.
I have supposed that FIR functions are already orthogonalised functions but
in FEAT gui there is the possibility to select this option ("Orthogonalise
basis functions wrt each other")
Could someone tell me when it is necessary?
thanks in advance.
Serena
