In fi >= non-fi, or non-fi >= fi, the non-fi must be a constant

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.

Thank you Walter, your advise helped me to solve this problem.

I just wrote the following commands, and the problem fixed

x=fi (x,true,16,16);

jj=fi (jj,true,16,16);

dears, how can I make the variables as fixed point?

[Walter Roberson]

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.
