Dear all, While teaching numerical analysis using J for half a semester (then COVID started), I have amassed some J code chunks that do something useful, while avoiding J magic as much as possible. I thought I would turn them into a simple J tutorial that might benefit other newcomers like myself. Though I was hooked(!) by the wow-factor of J, I continued to wonder for a long time as to why I should learn J. What benefit does it give me other than writing code that is one tenth the size of a program in another language (and takes about 20 times more time to write and debug)? Finally, I think I have found an answer that I can explain to a beginner in a few words.
My tutorial is written from that perspective. It would be great if the experts in this forum could please take a quick look at the tutorial and tell me if my approach would do more harm than good to newcomers. The tutorial is at https://arnabc74.github.io/jsoft/ It is still growing. Thanks and regards, Arnab ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
