Hello There,
I'm converting a Matlab (.m) file to fixed point
"Function call failed."
"In fi <= non-fi, or non-fi <= fi, the non-fi must be a constant."
Here is my code -----------------
x=amp*sin_vec(2*pi*f*t); % Sinusoid input singal (Hz)
jj=-(amp-Delta):Delta:(amp-Delta);
for j=1:jx
for k=1:1:km
if (x(k)>=jj(j)) % <---- error at this line
end
end

One of those two variables, x or jj, is in fixed point and the other one is not. You need to make both of them fixed point.

Tamer showed
x=fi (x,true,16,16);
which is an example of making x into a fi. You would need to adjust the parameters of the fi() call to be appropriate for the situation.
