- Function File: W = gram (sys, mode)
- Function File: Wc = gram (a, b)
gram (sys, "c")returns the controllability gramian of the (continuous- or discrete-time) system sys.gram (sys, "o")returns the observability gramian of the (continuous- or discrete-time) system sys.gram (a, b)returns the controllability gramian Wc of the continuous-time system dx/dt = a x + b u; i.e., Wc satisfies a Wc + m Wc' + b b' = 0.
