Inverse hyperbolic secant
Y = asech(X)
returns the inverse hyperbolic secant for each element of
asech function operates element-wise on arrays. The function's domains and ranges include complex values. All angles are in radians.
Graph the inverse hyperbolic secant over the domain .
The hyperbolic inverse secant can be defined as
