For example, what are matrix aggregating methods and can you give a description for each one more elaborately?
Is this similar to chemical fingerprints or not at all?

Creating a system with complex state matrices is sometimes needed (for example when you are working in a diagonal basis), but unfortunately python-control is missing this functionality right now.

substituting using a matrix (not Options, not a ring map) can still give the wrong/unexpected answer. Here are two situations (one over QQ, the other over CC_53).
It should be easy to fix this, Dan,…

Nicolas Thiéry and I have two rather different "packages" (at this moment, badly documented research code) that implement various operations on lists of vectors which are not given as lists of numbe…

Hey Justin, just had a chat with @kburns on spin-weighted spherical harmonics, which
1) remove the cos scaling when calculating gradients (convenience and simplicity)
2) simplify meridional gradi…

Just talked with @fieker: we have `syllables(g::Union{FPGroupElem, SubFPGroupElem})` and `letters(g::FPGroupElem)`
1. [ ] both of these should be available for `FPGroupElem` *and* `SubFPGroupElem…

Hi,
I am trying to symbolically compute the determinant of a 50x50 matrix using the Berkowitz method on a multi-core machine. It parallelizes on one of the machines I tried but does not use all the…

In Sage, matrix arithmetic over finite fields is fast in the following cases:
* Prime fields, using linbox (#4260) resp. `M4RI` over `GF(2)`
* `GF(2^e)`, using `M4RIE` (#9562)
In all other cases, …

SymPy handles eigenvalues of symbolic matrices, provided that they are not too large. Loading GenericLinearAlgebra and trying the same with Symbolics results in
```julia

Symbolic expressions may be part of type-neutral computations, e.g. matrices, polynomials. Developers do not expect proof machinery to crank up when writing `if x!=0`, but this is just what happens.…
