BAUMGARTNER2016_GRADIENTEXTRACTION - Extraction of positive spectral gradients

Usage:

[gp,gfc] = baumgartner2016_gradientextraction(mp,fc)

Input parameters:

mp discharge rate profile
fc center frequencies

Output parameters:

gp positive spectral gradient profile. Fields: gp.m for magnitude and gp.sd for standard deviation. Dimensions (4-6 optional): 1) frequency, 2) position (polar angle), 3) channel (L/R), 4) fiber type, 5) time frame.
gfc center frequencies of gradient profile

Description:

baumgartner2016_gradientextraction(...) is a spectral cue extractor inspired by functionality of dorsal cochlear nucleus in cats.
