Hui & Iverson (1991) The J Dictionary. http://cs.nyu.edu/courses/fall05/G22.2110-001/dictionary.pdf http://cs.nyu.edu/courses/fall05/G22.2110-001/dictionary.pdf This is the reason to learn J. It is a clean, fast course in a programming style that puts linear algebraic concepts at its heart. If you are interested in functional programming, work through this book. The "tutorial" part is about 60 pages, which should be worked through, and the dictionary part about 150 pages, which can be dipped into.
