Computes a smooth regularized solution of an ill-posed discrete linear inverse problem.

This package computes a smooth regularized solution of an ill-posed linear inverse problem by a non-linear constraint minimization algorithm using the L-curve criterion. Implemented regularization schemes are Tikhonov, Tikhonov-Phillips, and quadratic variation for 2D problems (-> Wendlandt, M., Van Beek, J.D., Suter, U.W., Meier, B.H., "Determination of orientational order in deformed glassy PMMA from solid-state NMR data."
