Questions where the notion matrix has an important or crucial role (for the latter, note the tag matrix-theory for potential use). Matrices appear in various parts of mathematics, and this tag is typically combined with other tags to make the general subject clear, such as an appropriate top-level tag ra.rings-and-algebras, co.combinatorics, etc. and other tags that might be applicable. There are also several more specialized tags concerning matrices.

Finding generators of matrix subgroups
I am particularly interested in Sp$(2n,\mathbb{Z})$, but I think an answer for a more general set of matrices would help. … Neither transvections nor elementary symplectic matrices are in $C(D)$. When $D$ is the specific matrix of interest, I can write all matrices in $C(D)$ in a explicit form in terms of 8 variables. …
