## Computes the Coefficients of a Hamming Window.

### Description

The filter coefficients w(i) of a Hamming window of length `n` are computed according to the formula

w(i) = 0.54 - 0.46*cos(2*pi*i/(n-1))

### Usage

    hamming.window(n)

### Arguments

`n` | The length of the window.

### Value

A vector containing the filter coefficients.
