# csc, csch

## Purpose

Cosecant and hyperbolic cosecant.

## Synopsis

    Y = csc(X)
    Y = csch(X)

## Description

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

`csc(X)` returns the cosecant for each element of `X`.

`csch(X)` returns the hyperbolic cosecant for each element of `X`.
