The Ricci-notation tensor (RT) framework [1] comprises a dual-variant index algebra, aligned with the Ricci notation of non-Euclidean geometry but designed for numeric purposes, as well as codesigned object-oriented software, called the RTToolbox for MATLAB. Compared to a numeric tensor (NT) predecessor [2, 3, 4], the RT framework enables superior ways to model imaging problems and to thereby develop solutions. Although this release of the RTToolbox does not address sparsity, the RT framework is theoretically capable of leveraging ideas demonstrated with the NT framework [5].
