Hi, I want to use eigs() to get the largest eigenvalue of a huge dense symmetric matrix.(50k by 50k) I can find eigs() in the documentation of Julia 0.6.4 , but cannot find it in Julia 1.0.4 or 1.0.1. Could you please tell me how I can use eigs() in v1.0 Julia? Thanks The reason why I want to u…

From the other topic: [image] Special method for finding eigenvalues of a large sparse symmetric matrix? eigs has moved to Arpack.jl. Documentation is here: Home · Arpack.jl .

do this, then these functions Linear Algebra · The Julia Language are available using LinearAlgebra

Hi,thanks for your reply. But there is no eigs().

Yes I know. They are using BLAS function LAPACK.syevr!, which is slow for large symmetric matrix.

[image] tkoolen: eigs has moved to Arpack.jl. Documentation is here: Home · Arpack.jl . that would be your function (if you are unfamiliar with the new package manager…) julia> using Pkg; Pkg.add("Arpack"); then using Arpack

Where is `eigs()` in Julia 1.0 version?
