Y = log10 (X) returns the common logarithm of each element in array X . The function accepts both real and complex inputs. For real values of X in the interval (0, Inf ), log10 returns real values in the interval ( -Inf , Inf ). For complex and negative real values of X, the log10 function returns complex values.

2. When plotting, why do we need to plot with 10*log10(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, 10*log10(pxx), fyy, 10*log10(pyy)) but the yrange is different. LOG vs LOG10 plot .
