[scilab-Users] Scifunc block

[Collette yann]

Hello,

Algebric loops happen when you loop a direct feedthrough input. In your 
loop, you must have some kind of delay to avoid this feedthrough.
In the diagram alg_loop_1.xcos, the input is directly linked to the 
output via the sin function (no delay). Xcos can't simulate this diagram 
because of this direct loop.
In the diagram alg_loop_1.xcos, I added a delay in the direct line. Now, 
there is some delay, no more direct feedthrough. And Xcos can simulate 
this diagram.
