This dataset belongs to the paper "A minimal hyperbolic system for unstable shock waves" (doi:10.1016/j.cnsns.2018.10.022 Format. Dataset is in the npz file, which is NumPy Zip binary file format, which can be read with function `np.load(filename)`. Reason for uploading. It was a part of the Git repository https://github.com/dmitry-kabanov/fickettmodel-reproducibility before, but it was noticed that Git LFS objects require special treatment, hence, for simplicity, it is uploaded here and the corresponding Makefile takes care of downloading it.
