ACOSH Inverse Hyperbolic Cosine Function

Section: Mathematical Functions


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.

Function Internals

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');
