OCaml Math Library

%%VERSION%%

A collection of OCaml Math and Statistics functions. The API is available online.

Goals

1. Perform simple and sophisticated mathematical and statistical analysis inside of (mostly) OCaml. Please see Oml_full section for details.
2. Have a descriptive, simple, and typed approach to those algorithms.
   • descriptive: what a function does should be easy to understand from the type and name.
   • simple: don't worry about the corner cases of the algorithms, until you have to.
   • typed: obviously.
3. Well tested. There are a subtle dependency between float capabilities and these algorithms. The test suite aims to provide bounds as well as a benchmark for comparing algorithms.
4. Informative examples.

Building

• make setup will opam install the necessary packages for Oml_full.
• make build will compile source.
• make test for tests.
  • We use Kaputt as the testing framework. Tests are found in *.mlt files and are joined with their respective source files only when building a test target.
  • make TEST={ModuleName} test will run the test in ModuleName, ex make TEST=Descriptive test
  • make setup_test will install packages necessary for testing.
• make covered_test for Bisect_ppx instrumented test coverage.

Oml_full

Oml_full is a superset of Oml that includes C and/or Fortran dependencies. It is generally more useful and incorporates Oml in a typed equivalent way. The goal is to provide a flexible end-user target for those who don't need C dependent functionality.

Dependencies

For the "full" Oml package make setup will opam install these:

• Lacaml for BLAS/LAPACK bindings.

• LBFGS for bindings to LBFGS optimization routines.

• ocephes for special functions.

  And for testing:

• Kaputt for testing.

• Bisect_ppx for code coverage.

Contributing

Anything within the problem domain is welcome.

Questions, Bugs, Issues

The best place to discuss Oml is within Github's issues (even for questions).
