asec, asech

Purpose

Inverse secant and inverse hyperbolic secant.

Synopsis

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

Description

asec and asech operate element-wise on matrices. Their domains and ranges include complex values. All angles are in radians.

asec(X) returns the inverse secant for each element of X.

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