Proble in implementing simple ''C Block 2'' in Xcos.

[sanjeev pandey]

Hi users,

I am still not able to figure out the problem in using the C Block 2 in the
xcos model, and also the similar model does not seem to work on Scicos
(Scicoslab 4-4). Can someone guide me in this regard. Thanks in
anticipation.

Best Regards,

Sanjeev
