Stephane,

Thanks for your prompt reply.

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).
