Software
On this page you can find software (written in MATLAB) that has been used in some of my research. Some code files are better written than others. The hope here is to prevent one from having to reinvent the wheel when working on new research.

Associated code for the work: Iterative reconstruction methods for cosmological x-ray tomography
Numerical software of the discrete linearized forward tomography operator that can be used to model the numerical inversion of the light ray transform. Can be used in test problems such as the reconstruction of gravitational anomalies (e.g., cosmological strings).

Associated code for the work: Range restricted iterative methods for the solution of linear discrete ill-posed problems
A package of generalized minimum residual (GMRES) functions and scripts which solve both linear and block linear discrete ill-posed problems. All functions terminate according to the discrepancy principle, but can easily be altered to terminate according to other criterion.

Associated code for the work: An Arnoldi-based preconditioner for iterated Tikhonov regularization
The package contains the basic function for the Iterated Arnoldi-Tikhonov (IAT) method. To reproduce some of the examples from the paper, the software package IR-Tools is needed. A test function in the package requires IR-Tools.
