# acot, acoth

## Purpose

Inverse cotangent and inverse hyperbolic cotangent.

## Synopsis

    Y = acot(X)
    Y = acoth(X)

## Description

`acot` and `acoth` operate element-wise on matrices. Their domains and ranges include complex values. All angles are in radians.

`acot(X)` returns the inverse cotangent for each element of `X`.

`acoth(X)` returns the inverse hyperbolic cotangent for each element of `X`.
