generate_feature_armadillo: This function creates K shifts of a neural events vector...

In PennStateDEPENdLab/dependlab: Useful functions for the UNC Chapel Hill DEPENd Lab (Director: Michael Hallquist)

This function creates K shifts of a neural events vector according to the kernel length, K.

Description

This function creates K shifts of a neural events vector according to the kernel length, K.

Arguments

encoding	The neural events vector (same length as BOLD time series)
K	The length of the kernel

Details

This is an internal function that is used inside a while loop by deconvolve_nlreg. Profiling of the algorithm revealed that this is the primary bottleneck, so I ported it to an Rcpp function

Value

A matrix of length(encoding) rows and K columns, where each column contains a successively lagged copy of the encoding vector
