I am using simulink user defined block to realise a difference equation. The function is defined as shown below.
function y = fcn(u)
a = [1 -2 1]; % left hand side of difference equation
b = [0 1 2]; % right hand side of difference equation
y=filter(b,a,u);
When I use this block independenly with some array as input, I am able to get the expected values. But when I use this block in another design, the output is always zero though the input is changing. Any suggestions on how to debug this ?

and what is the value of y if you execute code line by line during breakpoint?
