This package is deprecated and archived, and MKL support is available in Arpack.jl through Libblastrampoline.
This repo contains Arpack built against the MKL binaries. The module presents as ArpackMKL to Julia, but the underlying binary is still called libarpack.
In interactive use, you can alias const Arpack = ArpackMKL after loading the module.
The official Intel MKL distribution needs to be installed on your system to load the MKL-built Arpack. And the Julia MKL.jl should also be installed.
