Log Base 10 of Numeric and Symbolic Input
Compute the log base 10 of numeric input.
log10(20)
ans = 1.3010
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 fLog10 = double(fLog10)
fLog10 = 1.3979
