For JuMP-dev 2024, I wanted to give the elapsed time to solve a very large optimization problem with Ipopt and different linear solvers (MUMPS, SPRAL, MA27, MA57) but I got a segmentation fault for SP…

In a discussion with my friend @skieninger about the speed of sparse linear solvers of Matlab versus Python for solving a large system of equation (around 1e6) , we compared the backslash solver of Ma…

In #15422 there is a system of equations identified which runs into problem with `nonlinsolve` that might be resolved, but there is also the issue that systems of equations may be partially linear and…

Would like to be able to do this for the pressure-like field Phi, computed when stress Normalization is active in IBFE.

The Iterative Solver lab references a lab on linear systems that could be useful to solve problem 5. After looking for it in Bootcamp 2018, I could not find it. Is it in a specific folder?

It looks like there's no support for array and matrix operations in `linear_expansion`, e.g. `broadcast`.
I also have found that the workaround of performing `scalarize` on everything prior to `lin…

Dear MFEM community,
We are developing a new code based on MFEM to simu…

While standard linear systems seem adequately supported, there seems to be no way to differentiate expressions involving the cholesky decomposition. I believe the decomposition itself might be support…

Patch implements solving a linear system of equations in the most naive way possible, just augmenting the matrix and row-reducing.
For fields like `ZZ`, `QQ`, and integers mod p, this can be 3% to …
