Window Function

Description

Generates a window function of a given type and length.

Usage

windowfunc (npoints, type = 'hann', parameter = -1)

Arguments

`npoints`	The desired window length, in points. If a vector is given, the window will have the same length as the vector.
`type`	A string indicating the type of window desired. For the sake of simplicity, all window names are in lowercase. Supported types are: rectangular, hann, hamming, cosine, bartlett, gausian, and kaiser.
`parameter`	The parameter necessary to generate the window, if appropriate. At the moment, the only windows that require parameters are the Kaiser and Gaussian windows. By default, these are set to 2 for kaiser and 0.4 for gaussian windows.

Details

A window function is generated, of the type and length specified by the user. This is returned as a numeric vector.
