sech function operates element-wise on arrays. The function's domains and ranges include complex values. All angles are in radians.
Y = sech(X)
returns an array the same size as
X containing the hyperbolic secant of the elements of
Graph the hyperbolic secant over the domain
sech uses this algorithm.
The secant can be defined as
