OpenBLAS downloaded and first investigation

Downloaded OpenBLAS. This can be used because LAPACK (and BLAS) are included – latest versions (3.6.0) so this can be build uising Jouk Jansen’s files. Next it is finding out what can be done in Numpy.
Also got MatPlotLib – this contains three C/C++ packages that are required – and these may also be covered by Jouk Jansen – and for matPlotlib it is just a number of C sources, it is mainly a number of Python aources. This should also be possible.
NumPy itself is mostly Python – just some C sources
