asec

Inverse secant in radians

Syntax and Description

asec(X) returns the inverse secant (sec^-1) of the elements of X. The asec function operates element-wise on arrays. For real elements of X in the interval [-Inf,-1] and [1,Inf], asec returns values in the interval [0,pi]. For real values of X in the interval [-1,1] and for complex values of X, asec returns complex values. All angles are in radians.
