Hi Stephen,
whne loading the DCM file I have something like:
DCM =
a: [4x4 double]
b: [4x4x3 double]
c: [4x3 double]
d: [4x4x0 double]
U: [1x1 struct]
Y: [1x1 struct]
v: 210
n: 4
TE: 0.0400
delays: [4x1 double]
options: [1x1 struct]
M: [1x1 struct]
Ce: [4x1 double]
Ep: [1x1 struct]
Cp: [85x85 double]
Pp: [1x1 struct]
Vp: [1x1 struct]
H1: [32x4x3 double]
K1: [32x4x3 double]
R: [210x4 double]
y: [210x4 double]
T: 0
F: -1.0783e+003
ID: 414.6879
AIC: 13.0189
BIC: -42.2084
xY: [1x4 struct]
DCM.a seems for me to be the definition of the driving inputs and
intrinsic connection...
cheers
