Commit Message

Fix GMRES memory usage (#131)

* Add improved versions of GMRES and CG

* Add preconditioners

* Add Hessenberg type

* Hessenberg solver

* Fix incorrect comment

* Benchmark Givens rotation + UpperTriangular vs \

* Rename to Hessenberg

* Use UnsafeVectorView when solving the small system

* Clean up some

* Add Identity preconditioner type

* Improve GMRES with specialized functions for preconditioners, unsafe views, and conditional logging

* Don't run by default

* Some default values for gmres bench

* Reduce the number of allocs slightly by solving the least-squares-problem with the Hessenberg matrix in-place

* Fix for complex numbers

* Move from Vector{Vector{T}} to Matrix{T} using views and make orthogonalization routine reusable

* Make the comparison fair and the matrix sparser to ~10 nonzeros per row

* Fix a bug for complex numbers

* Temporarily remove tests with matrices as preconditioner, since we don't have A_ldiv_B for them at the moment

* Add tests for various orthogonalization methods

* Fix a problem for complex numbers again

* Export Identity

* Add tests to runtests.jl

* Fix compatibility with Julia 0.5

* Override the current gmres method and move solve! to A_ldiv_B!
