This package allows the user to perform a (Linear) General Least Squares Inversion with EPIC Tikhonov regularization. EPIC stands for Equal a Posteriori Information Condition.
EPIC_LS includes 2 subpackages:
EPIC: codes to compute the EPIC for the general linear least squares problem.
LeastSquares: codes to solve the linear least squares problem and the general linear least squares problem (with linear regularization).
