ACOSH function

Description

Inverse hyperbolic cosine function. ACOSH(x) returns the inverse hyperbolic cosine of x. X must be greater than or equal to 1.

The argument x can be a real number, a complex number, or a matrix. When it is a matrix, the function returns a matrix with the same dimensions and with the ACOSH function applied to all elements.
