log2
function for its argument. The general
syntax for its use is
y = log2(x)
where 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.
log2
function over the interval [1,100]
:
--> x = linspace(1,100); --> plot(x,log2(x)) --> xlabel('x'); --> ylabel('log2(x)');
