Log base 10 of symbolic input
Compute the log base 10 of numeric input.
ans = 1.3010
Compute the log base 10 of symbolic input. The result is in terms of
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
subs, and then using
fLog10 = subs(fLog10,x,5); % x is 5 fLog10 = double(fLog10)
fLog10 = 1.3979
Input, specified as a number, vector, matrix, or array, or a symbolic number, variable, array, function, or expression.
