hamming (Signal Processing Toolbox)

Hamming window

Syntax

w = hamming(n)
w = hamming(n,'sflag')

Description

w = hamming(n) returns an n-point symmetric Hamming window in the column vector w. n should be a positive integer. The coefficients of a Hamming window are computed from the following equation.

w = hamming(n,'sflag') returns an n-point Hamming window using the window sampling specified by 'sflag', which can be either 'periodic' or 'symmetric' (the default). When 'periodic' is specified, hamming computes a length n+1 window and returns the first n points.

Note If you specify a one-point window (n=1), the value 1 is returned.

Examples

Create a 64-point Hamming window and display the result in WVTool:

```
N=64;
wvtool(hamming(N))
```
