(m,n)-Matrices are represented as vectors of length n. Each vector (a row) is itself a vector whose length is m. Vectors are actually implemented as dependent lists. We define basic operations for this datatype (addition, product, neutral elements O_n and I_n). We then prove the ring properties for these operations. The development uses Coq modules to specify the interface (the ring structure properties) as a signature. This development deals with dependent types and partial functions. Most of the functions are defined by dependent case analysis and some functions such as getting a column require the use of preconditions (to check whether we are within the bounds of the matrix).""" flags: light-uninstall url { src: "https://github.com/coq-contribs/matrices/archive/v8.10.0.tar.gz" checksum: "md5=c3f92319ece9a306765b922ba591bc3f" }

Dry install with the current Coq version:
opam install -y --show-action coq-matrices.8.10.0 coq.8.11.2
[NOTE] Package coq is already installed (current version is 8.11.2). The following dependencies couldn't be met: - coq-matrices -> coq < 8.11~ -> ocaml < 4.10 base of this switch (use `--unlock-base' to force) No solution found, exiting
Dry install without Coq/switch base, to test if the problem was incompatibility with the current Coq/OCaml version:
opam remove -y coq; opam install -y --show-action --unlock-base coq-matrices.8.10.0
