It is often useful to define linear operators on arbitrary linear spaces, not necessarily AbstractVectors (e.g. the discretization of a n-d PDE). At the moment this is not supported by LinearMaps.

KrylovKit.jl uses an absolute convergence criterion `norm(residual) < tol`. Some packages, like ArnoldiMethod.jl and Arpack.jl, use a slightly different criterion `norm(residual) < tol * |λ|` where `λ…

Hi JAX developers,
I'm wondering if it's possible to calculate `jvp` for intermediate variables defined in a function. Here's an example:
```
def f(x, params_1, params_2, params_3):
W1, …

This is a meta-issue for keeping track of progress on implementing differentiable higher-order functions from SciPy in JAX, e.g.,

### Describe your issue.
I am installing scipy from source on an HPC on top of python 3.11.6. The code builds without errors, but `scipy.test()` segfaults at `scipy/sparse/linalg/_eigen/arpack/tests/…

We currently employ the `lobpcg` solver from this Julia package in our [DFTK.jl](https://github.com/mfherbst/DFTK.jl) electronic structure theory code. In our observations, the current Cholesky-QR-bas…

Could you please consider specifying different representation types for matrix columns? It would address a lot of engineering needs. For example, together with the physical units library, we could imp…

Forward sensitivity speeds are currently held back by the parameter jacobian evaluations, which can be enormously expensive to compute for our problems (lots of parameters) without sparse differentiat…
