asec

Inverse secant of each element, with the result in radians.

Category: Mathematics > Elementary Math

Syntax

Y = asec(X)

Description

asec(X) equals acos(1 ./ X). For real abs(X) >= 1 the result is a real angle in [0, pi], and asec(1) is 0. For abs(X) < 1 the result is complex.

Input arguments

X

Numeric array of any size.

Output arguments

Y

Array of the same size as X, in radians. It is complex where abs(X) < 1.

Example

Inverse secant

asec([1 2 -2])

ans = 1×3
