Matlab Software for Regularization of Discrete Ill-Posed Problems

  • AIR Tools II is a Matlab package of algebraic iterative reconstruction methods for inverse problems.

  • IR Tools is a Matlab package of Iterative Regularization methods and test problems for linear inverse problems. The package is a collaborative effort with Silvia Gazzola, University of Bath, and James G. Nagy, Emory University.

  • Regularization Tools (Version 4.0 for Matlab 7.3) is a Matlab package for analysis and solution of discrete ill-posed problems. The software and the manual are available, as well as some additional functions that provide new functionality.

  • mxTV is a software package for Total Variation image reconstruction. The core software is written in C, and with mex interfact to Matlab.

  • TVReg is a software package for 3D tomography using Total Variation regularization. The core software is written in C, and with mex interfact to Matlab.

Matlab Software for Rank-Deficient Problems

  • UTV Tools is a package of 46 Matlab functions for computing and modifying rank-revealing decompositions, with focus on URV and ULV decompositions.

  • UTV Expansion Pack, with extensions and new algorithms, is also available.
