Create a Toeplitz matrix for hemodynamic response function (HRF) convolution.
Usage
hrf_toeplitz(hrf, time, len, sparse = FALSE)
Arguments
- hrf
The hemodynamic response function.
- time
A numeric vector representing the time points.
- len
The length of the output Toeplitz matrix.
- sparse
Logical, if TRUE, the output Toeplitz matrix is returned as a sparse matrix (default: FALSE).
Value
A Toeplitz matrix for HRF convolution.
