I would like to use J to work on data that is stored in HDF5 files (see http://www.hdfgroup.org/HDF5/). Has anybody worked on this before? Interfacing J to HDF5 should not be difficult in principle (it's just another C library), but it looks like a lot of work.
What else do you use for reading/writing data that is too big for plain text files? Konrad. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
