(merge sort) is log from n log n on base 2? I've learned in class that merge sort is O(n · log(n)), but I'm not clear on whether it's O(n · log2(n)) or O(n · log10(n)). Hur ställer jag in axelgränser globalt i MATLAB till min och max upplagda data?

log b (X)= log a (X)/log a (B) you can check this easily. ln (x) = log 10 (x)/log 10 (e) so, just write that code in matlab. my_ln= log 10 (number) / log 10 (exp (1)); you can also make it as a function and call it whenever you need it, function [val] = ln_fun (number)

2. When plotting, why do we need to plot with 10log10(pxx) instead of only using pxx? Even when I use either ways of plotting, I cant seem to emulate the yrange in the example plot (attached). The closest plot seems to be plot(fxx, 10log10(pxx), fyy, 10*log10(pyy)) but the yrange is different.
