X : column vector. Continuous state. Can be set to [] if zero.
13
U : column vector. Input. Can be set to [] if zero.
15
Y : column vector. Output. Can be set to [] if zero.
17
Indx :vector, index of entries of X that are not fixed. If all can

Indy :vector, index of entries of Y that are not fixed. If all can
