Just 10^ (log10 (x)) x = log10 (1000); 10^x. Varun on 15 May 2012. LOG vs LOG10 plot . Learn more about loglog, log10, log . You are so right..I just had trouble after I recalled that log(x) in Matlab means ln(x) in Maths. MATLAB will take the most recent definition (as it did in your code) and treat it as a variable rather than a function.

my_ln= log 10 (number) / log 10 (exp (1)); you can also make it as a function and call it whenever you need it, function [val] = ln_fun (number) example 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). Description The log10 function operates element-by-element on arrays.

The most common base of any logarithmic equation is always considered to be 10 if it is not specified. semilogx (X,Y) plots x - and y -coordinates using a base-10 logarithmic scale on the x -axis and a linear scale on the y -axis. To plot a set of coordinates connected by line segments, specify X and Y as vectors of the same length. To plot multiple sets of coordinates on the same set of axes, specify at least one of X or Y as a matrix.

For real values of X in the interval (0, Inf), log10 returns real values in the interval (-Inf, Inf). log10 (x) returns the logarithm to the base 10 of x.

Its domain includes complex numbers, which may lead to unexpected results if used unintentionally.
