Attempted to access som(5513.5); index must be a positive integer or logical

delay = 0.5; %atraso de 0.5s

echost = 0.7; %força do eco

D = delay*fs;

reverb_som = zeros(size(som));

for i = D+1:1:length(som);

      reverb_som(i) = som(i)+echost*som(i-D);

end;

I've tried rounding i but it still presents the same error. I've also tried switching i for a constant but it's still the same. I really don't know what to do, could you please give hand? Thanks.

D = round(delay*fs);

Thank you so much! It worked brilliantly.
