<p>Dear Josep</p>

<p>Check the size of your table. It is 16,387 points, I believe — i.e. 16,384 (a power of two) plus 3 guard points (1 at the beginning, 2 at the end). 20,000 isn’t a power of two, so sinesum looks for the largest power of two less than 20,000 (i.e. 16,384),
and you end up trying to scan past the end of the table.<br>
</p>
<p><br>
</p>
<p>If you give sinesum a power of two to chew on (it will add the guard points itself) and only scan the table less the guard points, you should be OK. I tested this with a table of 65,536 (+ 3) points, and it was fine.</p>

</p>
<p>I *think* that answer is error free. I hope it is helpful.</p>
