create_spike_matrix_term: Spike matrix creation

In JoKra1/papss: What the package does (short line)

Spike matrix creation

Description

Create basis part of the model matrix as described by Wood (2017). Essentially, this means creating a matrix with a column for each pulse location and to assign a pupil basis (convolved with that location) to each column.

Usage

create_spike_matrix_term(
  expanded_time,
  expand_by,
  time,
  pulse_locations,
  fact,
  n,
  t_max,
  f
)

Arguments

expanded_time	A numeric vector containing positive time values in ms, expanded by a certain amount of ms
expand_by	Expansion time in ms passed to papss::pupil_solve(expand_by=) divided by sample length in ms
time	A numeric vector containing positive time values in ms
pulse_locations	A numeric vector containing index values of pulse loc.
fact	The factor column from the data-frame passed to papss::pupil_solve()
n	Parameter defined by Hoeks & Levelt (number of laters)
t_max	Parameter defined by Hoeks & Levelt (response maximum in ms)
f	Parameter defined by Wierda et al. (scaling factor)
