Inverse hyperbolic secant


Y = asech(X)


Y = asech(X) returns the inverse hyperbolic secant for each element of X.

The asech function operates element-wise on arrays. The function's domains and ranges include complex values. All angles are in radians.

Inverse Hyperbolic Secant

For real values x in the domain 0<x1, the inverse hyperbolic secant satisfies


For complex numbers z=x+iy as well as real values in the regions <z0 and 1z<, the call asech(z) returns complex results.
