MATLAB Function Reference

asec, asech

Inverse secant and inverse hyperbolic secant

Syntax

Y = asec(X)
Y = asech(X)

Description

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.

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))
