Julia wrapper for the arpack library designed to solve large scale eigenvalue problems.
You can install Arpack.jl through the Julia package manager:
julia> Pkg.add("Arpack")Arpack.jl will use BinaryProvider.jl to automatically install the Arpack binaries.
If you get
ERROR: LoadError: LibraryProduct(nothing, ["libarpack"], :libarpack, "Prefix(~/.julia/packages/Arpack/cu5By/deps/usr)") is not satisfied, cannot generate deps.jl!
when building Arpack, it may be because your Julia installation uses your system
blas for which the symbols are not suffixed by _64_ while this is required by
the compiled binaries provided by BinaryProvider.jl.
This is notably the case on ArchLinux.
In these case, compile binaries that do not require this suffix as follows.
Download the source of the v3.5.0 of arpack-ng,
extract it in some <directory>, build it and do (note that you may need to
update cu6By to match the one printed in the error message printed above).
$ cp <directory>/arpack-ng-3.5.0/SRC/.libs/libarpack.so.2.0.0 ~/.julia/packages/Arpack/cu5By/deps/usr/lib/
$ julia -e 'import Pkg; Pkg.build("Arpack")'
