Hallo,
my problem is that i want to set the quantity log2(0), so as log2(0)==0 {normally it is log2(0)==-inf}. is there a simple way to do this?
Thanks you in advance.

Write your own log2 and call it:
function out = mylog2(in)
out = log2(in);
out(~in) = 0;
end
Add the F/E output options if desired.
It would be very dangerous to overload this function since it's probably used elsewhere.
