sspace and system functions

Jul 21, 2015 at 9:19 PM
We have a model where
[A,B,C,D,F,G,H,J,List,Nf] = system(gmuse);
size(A)
ans =
        1444        1444
[T,R,K,Z,H,D,U,Omg] = sspace(gmuse);
size(T)
ans =
        1414         481
size(R)
ans =
        1414         179
I am not sure why there are different number of rows in matrices A and T.
Isn't the list of variables the same for both system and sspace matrices?
