synopsis: "Ring properties for square matrices"
description: """
This contribution contains an operational formalization of square matrices.
(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)."""

trueDry install with the current Coq version:
opam install -y --show-action coq-matrices.8.8.0 coq.8.6.1[NOTE] Package coq is already installed (current version is 8.6.1).
The following dependencies couldn't be met:

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:
opam remove -y coq; opam install -y --show-action --unlock-base coq-matrices.8.8.0truetrueNo files were installed.
