I wonder if we should move the Woodbury and Bunch Kaufman out of Base into a LinearAlgebra.jl package. There all kinds of other stuff that could potentially be in there, like all the stuff from Golub …

Currently, `lu`, `chol`, `(\)`, etc. convert an `Array{Rational{Int64},2}` to `Array{Float64,2}` before doing any computation. These should actually compute the decompositions using rational arithmeti…

What steps will reproduce the problem?
1. import pyamg
2. pyamg.test()
3.
What is the expected output?
What do you see instead?

Hi.
I just found a bug in A_ldiv_B! when used with a sparse matrix
factored with lufact!
The error is trigered with
```
A = spzeros(3,3)
A[1,1] = 1
A[2,2] = 1
A[3,3] = 1
b = ones(3)
lufact!(A)

This is more of a placeholder. In theory it should be possible to use CUDA
(Nvidia's API for using a GPU for vector ops) to speed up several aspects of
processing here, since a lot is matrix ope…
