(Adapted from an off-line discussion)
Lapack is almost at a state where it can implement the full functionality of the current Solve.
I don’t think the current Solve function is idiomatic within mat…

As reported on the mailing list, we should make sure that `cholfact(SparseMatrixCSC)` returns the PosDefException if the matrix is not symmetric and positive definite.

It occurs to me that, in the heterogeneous key/value type case, #12327/#12261 causes us to lose type information. Consider basically any code that uses the `for (k, v) in dict` idiom, e.g.:
``` julia…

There's been a lot of debate about whether we should incorporate sparse vectors into Julia 0.4.
Here are three options:
- (A) Use `SparseMatrixCSC` to emulate a sparse vector. This, as many have poin…

Do you plan to implement the Singular Value Decomposition based on cuSolver anytime soon?
Thanks!

Rather than rolling our own sparse-matrix library, it seems like it would be much better to use [PETSc](http://www.mcs.anl.gov/petsc/), which is the de-facto standard here.
PETSc would give us access…

For reference, the code I blame is
``` javascript

It would be nice to have linear-algebra functions for `BigFloat` (possibly as an external package?) and other generic `Number` types.
~~Currently, `\` on a `BigFloat` converts to `Float64`; `eig` and…

Hi,
matlab and octave call Tim Davis sparse qr routine (for the sparse case). I guess
that is the intention for julia also, but does not exist on the versions of julia I've
succeeded in downloadi…

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 …
