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. example.
Numpy seems to take a cue from MATLAB/Octave and uses log to be "log base e" or ln. Also like MATLAB/Octave, Numpy does not offer a logarithmic function for an arbitrary base. If you find log confusing you can create your own object ln that refers to the numpy.log function: >>> import numpy as np. >>> from math import e.

2 paź 2021 · More generally, just remember the properties of logarithms and use either log(), log10(), or log2() to compute the arbitrary base-n logarithm.
Compute the log base 10 of symbolic input. The result is in terms of log. syms x. f = x^2; fLog10 = log10(f) fLog10 =. log(x^2)/log(10) Convert symbolic output to double by substituting for x with a number using subs, and then using double. fLog10 = subs(fLog10,x,5); % x is 5.
The Python math.log10() method is used to retrieve the logarithm of the given number with base 10. According to the mathematical definition, a logarithmic function of a number produces a result which is raised by its base to achieve the said number.
