To create a plot using a log (base 10) scale for both the x-axis and and the y-axis you can use the function loglog Actually MATLAB does not have a universal logarithm function that works with any arbitrary base. To create a plot with a linear scale on the x-axis and a log (base 10) scale on the x-axis you can use the function semilogx. I am trying to figure out why there is no line plotted on my graph once this script is run The MATLAB M-file used to create this plot is experr.m. log10(x) rewrites logarithms to the base 10 in terms of the natural logarithm: log10(x) = ln(x)/ln(10) log base 10 plot. The logarithm to the base 10 is defined for all complex arguments x в‰ 0. Mathematically, log10(x) is equivalent to log(10, x). Log10(x) represents the logarithm of x to the base 10. 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. Compute the log base 10 of symbolic input. Compute the log base 10 of numeric input. simplify (yVal) ans = Log Base 10 of Numeric and Symbolic Input.

Substitute the symbolic variable x with a number by using subs. The result is in terms of the natural logarithm log function. I tried playing around with the axis thinking that maybe that was why I wasn't seeing anything plotted however, this did not resolve my issue Compute the base-2 logarithm of a symbolic input. Good day, I am trying to figure out why there is no line plotted on my graph once this script is run.

MATLAB: How to plot the log to base 10 of absolute value If it really bothers you in Matlab, you can assign ln () as the natural log by using. Though ln ()'s origins come from Latin, logarithmus naturali, you could also say that log () without a base implies the natural log. Note that for many MATLAB versions log10 itself called log2 internally. Commented: Stephen Cobeldick on Accepted Answer: James Tursa.
