Often, we need some estimates of the wave speeds, e.g.
- for CFL-based time step control
- for numerical fluxes like local Lax-Friedrichs, Harten-Lax-van Leer
In principle, multiple estimate …

As discussed at http://thread.gmane.org/gmane.comp.lang.r.lme4.devel/10773
I can see adding `check.nAGQ` to our list of checks (i.e. it could be "ignore", "warning", or "stop"), or something.
Thoug…

It would be nice to have support for generating Gauss–Kronrod points and weights for the weight functions in FastGaussQuadrature, at least when they exist, in order to have an error estimate from the …

Dear all,
I tried setting the option allow_rules_with_negative_weights = FALSE for THIRD-order Gauss-like rule for my mesh with TET10 elements, and it seems to crash LAPACK. The actual error messag…

The following snippet tries to assemble the simplest linear form with Quadrature elements on a quadrilateral mesh, throwing `ValueError: Mismatch of quadrature points!`:

I'm trying to use a variable with a uniform integer distribution with the SC and PCE samplers. (Eventually, I want a distribution of {0, 1} for a random binary value).

This issue is going to remain permanently open. It should not ever be closed. Its purpose is to track known test failure cases, and their causes.
Something can be added to this list _only_ if there…

I use weighted quadrature in my research, and I was thinking of using quadax to replace scipy.integrate.quad in my work. I'd be interested in contributing a feature that handles weighted integration. …

I have done some small optimisations of the original `elementary_matrix` function in https://github.com/WaveProp/WaveProp/commit/621dd70d261a17a541468acbe66edffa2bbd1185. The changes include:

The following is incorrect as QuadratureFunctionCoefficient only considers integration rules for volumetric terms.
