Inverse secant and inverse hyperbolic secant
Syntax
Y = asec(X) Y = asech(X)
Description
Theasec 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.
Examples
Graph the inverse secant over the domains
and 
and the inverse hyperbolic secant over the domain 
x1 = -5:0.01:-1; x2 = 1:0.01:5;plot(x1,asec(x1),x2,asec(x2))x = 0.01:0.001:1; plot(x,asech(x))
