acosh - Inverse hyperbolic cosine

Syntax

Description

Y = acosh(X) returns the inverse hyperbolic cosine for each element of X.

The acosh function operates element-wise on arrays. The function's domains and ranges include complex values. All angles are in radians.

Examples

Graph the inverse hyperbolic cosine function over the domain –1 ≤ x ≤ π.

x = 1:pi/40:pi; 
plot(x,acosh(x)), grid on

Definitions

The hyperbolic inverse cosine can be defined as
