# cot, coth

## Purpose

Cotangent and hyperbolic cotangent.

## Synopsis

    Y = cot(X)
    Y = coth(X)

## Description

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

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

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