This package contains Matlab code for spectral CT one-step inversion. It consists in implementations of five different methods, which are compared in the paper "Comparison of five one-step reconstruction algorithms for spectral CT", by Cyril Mory, Bruno Sixou, Salim Si-mohamed, Loïc Boussel and Simon Rit. You can access it in its submitted version following this link: https://hal.archives-ouvertes.fr/hal-01760845/document

The "Notes" folder contains a LaTeX document with our notes, which should help the interested reader to re-do the math of each of the five original papers in which the compared methods are described. You can have it compiled on-the-fly by visiting this address: https://latexonline.cc/compile?git=https%3A%2F%2Fgithub.com%2Fcyrilmory%2FOneStepSpectralCT&target=Notes%2FNotes.tex&command=pdflatex&

We appreciate any relevant contribution to either the Matlab code or the notes. Please submit them via a pull request on github.
