As the title indicates, over multiple runs of my program, I get different values of trans and est. Are these local minimum? If so how do I get the optimal one?
NOTE - They all have the same starting value of trans and est.
Thanks!
Edit: I realized…

Applying deconv for a large dataset
For my program on BCH decoding I had to polynomially divide the corrected BCH code with the generator matrix for the final decoded input. I did the same as follows:
for j=1:num_blocks,
op4(:,j)=mod(deconv(op3(:,j)',gen),2)';
end
where op3…
