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.
