(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/v8.7.0.tar.gz" checksum: "md5=a1e782ff3781cecead825be0ebde0fbc" }

Dry install with the current Coq version:

- Command
`opam install -y --show-action coq-matrices.8.7.0 coq.8.11.dev`

- Return code
- 5120
- Output
[NOTE] Package coq is already installed (current version is 8.11.dev). The following dependencies couldn't be met: - coq-matrices -> coq < 8.8~ -> ocaml < 4.05.0 base of this switch (use `--unlock-base' to force) Your request can't be satisfied: - No available version of coq satisfies the constraints No solution found, exiting

Dry install without Coq/switch base, to test if the problem was incompatibility with the current Coq/OCaml version:

- Command
`opam remove -y coq; opam install -y --show-action --unlock-base coq-matrices.8.7.0`
