asinh

Inverse hyperbolic sine

Syntax

• Y = asinh(X)
  

Description

Y = asinh(X) returns the inverse hyperbolic sine for each element of X.

The asinh 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 sine function over the domain .

• x = -5:.01:5; 
  plot(x,asinh(x)), grid on
  

Definition

The hyperbolic inverse sine can be defined as

Algorithm

asinh uses FDLIBM, which was developed at SunSoft, a Sun Microsystems, Inc. business, by Kwok C. Ng, and others. For information about FDLIBM, see http://www.netlib.org.
