Computes the inverse hyperbolic cosine of its argument. The general syntax for its use is
y = acosh(x)
where x
is an n
-dimensional array of numerical type.
The acosh
function is computed from the formula
where the log
(and square root) is taken in its most general sense.
Here is a simple plot of the inverse hyperbolic cosine function
--> x = linspace(1,pi); --> plot(x,acosh(x)); grid('on');
