Function Synopsis

NN=struc(NA,NB,NK)

Help text

STRUC  generates typical structure matrices for ARXSTRUC and IVSTRUC.
   NN = STRUC(NA,NB,NK)

   NA, NB and NK are vectors containing the orders na, nb and delays nk
   to be tested. See HELP ARX for an explanation of na, nb and nk.
   NN is returned as a matrix containing all combinations of these
   orders and delays. The function is intended for single input systems
   only.

   See also ARXSTRUC, IVSTRUC and SELSTRUC for further information
