So, in Ubuntu, to install libatlas, one does:
sudo apt-get install libatlas3-base and then
sudo update-alternatives --config libblas.so.3 and then one picks one of the various libblas.so.3 options shown there.
Likewise, doing:
sudo update-alternatives --config liblapack.so.3 allows one to pick on of the various available options for liblapack.so.3.
Now, my question is how does one do the same thing in Fedora-23? For starters, I think (is this correct?) that to install atlas, one does:
sudo dnf install atlas-devel does this install atlas? And is there (as in ubuntu) a way to select which liblapack.so.3 and libblas.so.3 ones uses?
