Mexican Hat HRF (hemodynamic response function)

The hrf_mexhat function computes the Mexican hat wavelet-based HRF (hemodynamic response function) at given time points t.

Usage

hrf_mexhat(t, mean = 6, sd = 2)

Arguments

t

A vector of time points.

mean

A numeric value representing the mean of the Mexican hat wavelet. Default value is 6.

sd

A numeric value representing the standard deviation of the Mexican hat wavelet. Default value is 2.

Value

A numeric vector representing the Mexican hat wavelet-based HRF at the given time points t.
