CoinUtils (Coin-OR Utilities) is an open-source collection of classes and functions that are generally useful to more than one COIN-OR project. These utilities include:

• classes for storing and manipulating sparse matrices and vectors,
• performing matrix factorization,
• parsing input files in standard formats, e.g. MPS,
• building representations of mathematical programs,
• performing simple presolve operations,
• warm starting algorithms for mathematical programs, and
• comparing floating point numbers with a tolerance, among others.
