Hola @IgnacioAcunaF, tengo implementado un scraper usando [`matrix`](https://docs.github.com/en/actions/using-jobs/using-a-matrix-for-your-jobs) para correr en paralelo distintos trabajos `A.py`, `B.py`,..., `F.py`. - En mi caso los resultados de cada scraper generaban un archivo nuevo...
Ahí también podría ser muy útil: https://github.com/MinCiencia/Datos-CambioClimatico/blob/main/src/actualizar_github.py saludos!
Dear all, do you have any suggestion concerning this PR? Thank you!
> @pescap what do you think about renaming `H`? In terms of code readability I'd like to keep `H` for the upper Hessenbergs in order to match the typical notation...
Hi @lukeolson, let me know if you have further questions. As soon as the PR is merged, I plan to create an issue to discuss and compare l2- and H^1-based...
I sent a PR for the H-norm `_gmres_mgs`. I attach below a simple code that tests it. I could add a similar proceeding to [`test_krylov.py`](https://github.com/pyamg/pyamg/blob/main/pyamg/krylov/tests/test_krylov.py) later on. So far, I...
``` import numpy as np import pyamg import scipy.linalg # Solving Ax=b with H-norm GMRES(k) is equivalent to solving # (H^{1/2}AH^{-1/2})(H^{1/2}x)=H^{1/2}b with Euclidean norm GMRES(k) N = 1000 A =...
According to [Householder orthogonalization with a non-standard inner product](https://arxiv.org/pdf/2104.04180.pdf) (Meiyue Shao), it sounds like Householder reflections for H-inner products are of the form (see section 2): ``` I - 2*w*conjugate(w)^T...
