asec, asech
Inverse secant and inverse hyperbolic secant
Y = asec(X) Y = asech(X)The
asec and asech functions operate element-wise on arrays. The functions' domains and ranges include complex values. All angles are in radians.
Y = asec(X)
returns the inverse secant (arcsecant) for each element of X.
Y = asech(X)
returns the inverse hyperbolic secant for each element of X.
Graph the inverse secant over the domains 
and 
and the inverse hyperbolic secant over the domain
