problems with S-function in simulink

I'm an italian student in mechanical engineering at Politecnico di Milano, I've got some problems with S-function in simulink.

My version is the 7.4.0 (matlab R2007 a), i'm using that software to implement a real time identification system.

I've created a S function that realizes two sequences of givens rotation, it works good if it is not connected with other simulink blocks. When I connect S-function block with others simu-blocks, the output is always a zeros matrix.

why does it happen? there are something to set?
