Description

Re: JuliaLang/julia#5840, JuliaLang/LinearAlgebra.jl#136, JuliaLang/julia#8240

We have a lot of easy targets to fill out the linear algebra functionality. These methods don't work at all. They don't have fallbacks to the dense method, even. Feel free to add more:

  • BunchKaufman
    • Matrix
    • det
    • logdet
  • LDLt{SymTridiagonal}
    • det
    • logdet
    • norm
    • tr
    • eigvals
    • eigvecs
    • svdvals
    • svd
    • cond
  • Hessenberg, UpperHessenberg
    • eigen, eigvals: #858
    • qr (mentioned in #625)
