Syntax

• NN = struc(NA,NB,NK)
  

Description

struc returns in NN the set of model structures comprised of all combinations of the orders and delays given in row vectors NA, NB, and NK. The format of NN is consistent with the input format used by arxstruc and ivstruc. The command is intended for single-input systems only.

Examples

The statement

• NN = struc(1:2,1:2,4:5);
  

produces

• NN =
   1  1  4
   1  1  5
   1  2  4
   1  2  5
   2  1  4
   2  1  5
