Caml is a general-purpose, powerful, high-level programming language with a large emphasis on speed and efficiency. A dialect of the ML programming language, it supports functional, imperative, and object-oriented programming styles. Caml has been developed and distributed by INRIA, a French research institute, since 1985.
The OCaml system is the main implementation of the Caml language. It has a very strong type-checking system, offers a powerful module system, automatic memory management, first-class functions, and adds a full-fledged object-oriented layer. OCaml includes a native-code compiler supporting numerous architectures, for high performance; a bytecode compiler, for increased portability; and an interactive loop, for experimentation and rapid development. OCaml’s integrated object system allows object-oriented programming without sacrificing the benefits of functional programming, parametric polymorphism, and type inference. The language is mature, producing efficient code and comes with a large set of general purpose as well as domain-specific libraries.
OCaml is often used for teaching programming, and by large corporations. OCaml benefits from a whole range of new tools and libraries, including OPAM (package manager), optimizing compilers, and development tools such as TypeRex and Merlin.
OCaml was written in 1996 by Xavier Leroy, Jérôme Vouillon, Damien Doligez, and Didier Rémy at INRIA in France.

1. OCaml tutorials by OCaml.org
Here’s a wide variety of OCaml tutorials.
2. How to wrap C functions to OCaml by Florent Monnier
This document is a small tutorial that introduces how to call C functions from OCaml. Which is useful if you want to make a mixed C and OCaml application, if you want to call some functions you need from a C library, or to write a complete binding to a C library.
3. Tutorial: OCaml for scientific computation by Dr. Thomas Fischbacher
Tutorial: OCaml for scientific computation covers most of the OCaml features that are used in the nsim library which is used by nmag.
4. Learn OCaml in Y minutes by Daniil Baturin
OCaml is a strictly evaluated functional language with some imperative features.
