After running the below code i am getting an error "This text contains non-empty top-level expressions. It appears to be a script."

x=real(signal);

l=length(x);

xin2(1)=1;

eqin(1)=x(1);

for i=1:(l-1)

eqin(i+1)=x(i+1)-xin2(i)+eqin(i);

xin2(i+1)=sign(eqin(i+1));

end

can anyone tell me what to change in the code so as to convert this code to verilog ....

Can you attach your whole script? Which line does the error appears on?

this is the whole script..and the error is "This text contains non-empty top-level expressions. It appears to be a script."

HDL Coder is expecting a function, rather than a script:
