All, In using 'readtable' as defined in the primer I find the following situation:
Reading in a square matrix from a file with each row of numbers on a line I always get the 'correct' answer when asking about the shape of the read in data, EXCEPT when the data has only one value per line ie is a vector or de-generate matrix if you will. In that case the shape comes back with a single number say N whereas I was expecting it to say 'N 1' and indeed the read in data is not available for linear algebra operations whereas data with more that one column is without further ado. Why does J not treat a column of numbers as a N by 1 'matrix' ie a vector rather than a list? (Pardon me if I sound like I am whining ;-) ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
