Even though I've fallen out of love with Matlab, its documentation is excellent. Brief description of the syntax for quick reference, a more detailed description, and finally detailed examples. Often there are references to the academic work behind the function and links to broader topics. Finally there's a bunch of related functions listed at the end which is great for discovering the vast array of Matlab's capabilities.
