Quaternion Function Reference

asinh

Inverse hyperbolic sine.
(Quaternion overloading of standard MATLAB® function)

Syntax

Y = asinh(X)

Description

asin(X) computes the inverse hyperbolic sine of its argument, which must be a real quaternion (asinh is not yet implemented for complexified quaternions).

This function is computed using the Matlab® function of the same name by first computing an isomorphic complex number. The result is then assigned the same quaternion axis as the original argument.

Examples

>> asinh(qi + qj + qk)
 
ans = 1.146 + 0.9069 * I + 0.9069 * J + 0.9069 * K
