• A should be a numeric array.
• It returns an array containing the logarithm (base 10) of each element of A.
• The output has the same size as A.
• log10(a) may be a complex number if a is complex or a negative real number.

Example

• Base-10 logarithms of random numbers and some special numbers.

Input

% Returning complex numbers.
log10([-inf rand + rand*i -rand])
% Returning real numbers.
log10([inf nan 0 rand])

Output

ans = 
 Inf    + 1.3644i   0.0067 + 0.3316i  -0.1378 + 1.3644i

ans = 1e-1 × 
 Inf      NaN     -Inf     -8.1722
