gabor: Generate Gabor function

In Rwave: Time-Frequency Analysis of 1-D Signals

Generate Gabor function

Description

Generates a Gabor for given location and frequency.

Usage

gabor(sigsize, location, frequency, scale)

Arguments

sigsize	length of the Gabor function.
location	position of the Gabor function.
frequency	frequency of the Gabor function.
scale	size parameter for the Gabor function. See details.

Details

The size parameter here corresponds to the standard deviation for a gaussian. In the Carmona (1998, eBook ISBN:978008053942) book, equation 3.23 has a different scale factor.

Value

complex 1D array of size sigsize.
