Consider a slightly modified first example found on page http://www.jsoftware.com/docs/help701/dictionary/d211.htm
]d=. (?.3 4$2)*?.3 4$100x 0 0 0 0 85 0 0 0 0 59 33 0 ] s=. $. d |domain error | ]s=. $.d 3!:0 d 64 Why do I get a domain error? Are sparse arrays not implemented for extended integers? I couldn't find anything about this topic in the forums. Any pointers and/or explanations will be hugely helpful. Thanks, Vijay. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
