ARPACK-NG is a collection of Fortran77 subroutines designed to solve
large scale eigenvalue problems.
This is a fork of ARPACK that is actively maintained. As such, this
package will conflict with the ARPACK package. Do not install both.
This requires a BLAS/LAPACK implementation. Choose one of these package sets:
* OpenBLAS (includes both a BLAS and a LAPACK implementation)
* atlas (includes both a BLAS and a LAPACK implementation)
* blas, lapack (the Netlib reference implementations)
If more than one set is installed (assuming there are no packaging conflicts)
then the auto-detection will use the first implementation from this list that
it finds. If in doubt, choose the Netlib reference implementations; other
packages that require a BLAS or LAPACK implementation may not build if they
are not configured to detect/use alternate implementations.
If the `make check` command fails, try switching to the Netlib reference
implementations, or comment out that command at your own risk.
