Hello, I proceed with my studies of J, well I have a couple of questions for you.
As far as I understand, а sparse matrix can't mapped as file, am I right? Second, what's the most optimal way of converting a table (i,j,value) into matrix, preferably a sparse one? Can't really get the clue... I am also interested in the process of reverse conversion... Nick. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
