Construct a list of covariance basis matrices for the noise model in
variational inversion. Mirrors SPM25's spm_Ce.
dcm_Ce(t, v = NULL, a = NULL)
Arguments
- t
Either a numeric vector of session lengths (defaults to AR basis)
or a string "ar" / "fast" selecting the basis type.
- v
Session lengths (when t is a string).
- a
AR coefficient (or sampling interval for FAST).
Value
A list of sparse Matrix objects.
