The presented software reproduce the numerical results of Inverse Problem paper. Software generate realisitc sythetic multi-energetic tomographic projection data and reconstruct it. Novel correlative multi-channel algorithm compared with other state-of-the-art reconstruction algorithms. Note that the GPU Nvidia card is required to use the software.
