spike-triggered covariance (STC) analysis - matlab code
description: Simple demonstration of spike-triggered average and spike-triggered covariance calculations on a simulated LNP-neuron example. Performs optional whitening of stimulus statistics (i.e. for use with correlated stimuli) and ridge regression (i.e. regularization) .
