LOG2 Base-2 Logarithm Function
Section: Mathematical Functions
log2function for its argument. The general syntax for its use is
y = log2(x)
x is an
n-dimensional array of numerical type.
Integer types are promoted to the
double type prior to
calculation of the
log2 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.
ExampleThe following piece of code plots the real-valued
log2function over the interval
--> x = linspace(1,100); --> plot(x,log2(x)) --> xlabel('x'); --> ylabel('log2(x)');
