Upen2DTool

Upen2DTool is a 2-dimensional (2D) inversion MATLAB® script package developed at the University of Bologna (Bologna, Italy), that processes 2D Nuclear Magnetic Resonance relaxometry data. Upen2DTool applies the Upen2D algorithm, the 2D extension of the Uniform PENalty principle, to compute locally adapted regularization parameters and approximate solutions by solving a sequence of regularized least squares problems.

The software is written in Matlab® 2018b script language and consists of a main folder ("Upen2DTool") containing the script files and two sub-folders: one with the data files ("DATA") and the other one ("output_files") with the output files creates by a run of the software. It comes also with a compiled version for windows (the executable version "Upen2DTool_Exe_ver.1.0" and the runtime MatLab® library are both available in the download area).
