Input Arguments

Identified model. If


Integer indices of N entries in the array 
Output Arguments

Statespace matrices that represent $$\begin{array}{l}x[k+1]=Ax[k]+Bu[k]+Ke[k];x[0]=x0;\\ y[k]=Cx[k]+Du[k]+e[k];\end{array}$$ If 

Initial state. If For other model types, If 

Uncertainties associated with the statespace matrices
The uncertainty matrices represents 1 standard deviation of uncertainty. If 

Uncertainty associated with the initial state.
