# acsc, acsch

## Purpose

Inverse cosecant and inverse hyperbolic cosecant.

## Synopsis

    Y = acsc(X)
    Y = acsch(X)

## Description

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

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

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