(see impulse for details).

When invoked with lefthand arguments,

[y,t,x] = initial(sys,x0)

[y,t,x] = initial(sys,x0,t)

return the output response y, the time vector t used for simulation, and the

state trajectories

x. No plot is drawn on the screen. The array y hasasmany

rows as time samples (length of

t) and as many columns as outputs. Similarly,

x has length(t) rows and as many columns as states.

Example Plot the response of the state-space model

to the initial condition

a = [-0.5572 -0.7814;0.7814 0];

c = [1.9691 6.4493];

x0 = [1 ; 0]
