Missing umf_extract(UmfpackLU{Complex{Float64},Int64},) for lufact() applied to sparse complex matrices

[jasax]

Hello,

In the quest to get complex algebra working in julia in Win7-64 (following issue JuliaLang/LinearAlgebra.jl#117), I turned to sparse matrices and lufact(). Apparently it was uncovered another glitch, which is the nonexistence of a method: "no method umf_extract(UmfpackLU{Complex{Float64},Int64},)"

So, it seems that no template for those types is present in umf_extract()...

Below is the test code and result.

Best Regards

Jose

N=4
J=0.0+1.0im

MR = rand(Float64,N,N)
MI = rand(Float64,N,N)

SpMR=sparse(MR)
SpMI=sparse(MI)
SpM=SpMR+J*SpMI
println("Sparse M \n",typeof(SpM))
println(SpM)

F=lufact(SpM)
println("F \n",typeof(F),"\n")

println(F[:L])
println(F[:U])
println(F[:p])
println(F[:q])
println(F[:Rs])

Looking into this now.

Thanks, Viral.
