[scilab-Users] time delay with syslin?

[Stephane Mottelet]

Hi Dean,

in the Matlab function the input time delay has to be approximated  
with a finite dimensionnal state-space model, which is  
series-connected with (A,B,C,D).
I am not sure that such a functionnality exists in syslin (but a time  
delay block exists in Xcos).
