[Ticket#2009101810000038] dcgain in scilab?

[Scilab Support]

Dear suhas deshpande,
 There is no ready to use function to compute DCgain, but in the regular cases
it is quite easy on can use the formulas 
 D-(C/A)*B for continuuos time state space systems or D+C/(eye(A)-A)*B for
discrete time systems
 
 For continuuous time transfert systems on can use horner(H,0) and for
discrete ones horner(H,1)

 1) How to calculate DC gain in scilab? matlab command i know is
dcgain(system) 
 
 2) When I execute tf2ss(system), the state space matrices are not in standard
form, how do i get the matrices in canonical form and companion form
 
 see  the canon and cont_frm functions
