pint.fitter.get_gls_mtcm_mtcy_fullcov

pint.fitter.get_gls_mtcm_mtcy_fullcov(cov: ndarray, M: ndarray, residuals: ndarray) → Tuple[ndarray, ndarray]

A utility function used by the GLS fitters.

Computes the matrix products mtcm = M^T C^-1 M and mtcy = M^T C^-1 y given the data covariance matrix (cov), timing model design matrix (M), and residuals y (residuals).
