Coq OPAMcoq-matrices
Ring properties for square matrices. 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).
