LOG10 Base-10 Logarithm Function

Section: Mathematical Functions


Computes the log10 function for its argument. The general syntax for its use is
  y = log10(x)

where x is an n-dimensional array of numerical type. Integer types are promoted to the double type prior to calculation of the log10 function. Output y is of the same size as the input x. For strictly positive, real inputs, the output type is the same as the input. For negative and complex arguments, the output is complex.


The following piece of code plots the real-valued log10 function over the interval [1,100]:
--> x = linspace(1,100);
--> plot(x,log10(x))
--> xlabel('x');
--> ylabel('log10(x)');
