Here is the scenario. I have the following data: (< every i. 2 5);<<every i. 3 5 +-----------+----------------+ |+-+-+-+-+-+|+--+--+--+--+--+| ||0|1|2|3|4|||0 |1 |2 |3 |4 || |+-+-+-+-+-+|+--+--+--+--+--+| ||5|6|7|8|9|||5 |6 |7 |8 |9 || |+-+-+-+-+-+|+--+--+--+--+--+| | ||10|11|12|13|14|| | |+--+--+--+--+--+| +-----------+----------------+
What I want to do is to get the data this way: +--+--+--+--+--+ |0 |1 |2 |3 |4 | +--+--+--+--+--+ |5 |6 |7 |8 |9 | +--+--+--+--+--+ |0 |1 |2 |3 |4 | +--+--+--+--+--+ |5 |6 |7 |8 |9 | +--+--+--+--+--+ |10|11|12|13|14| +--+--+--+--+--+ But if I try just unboxing the data, I would not get what I want (I even tried using "each" and "every" to no avail): $ >(< every i. 2 5);<<every i. 3 5 2 3 5 I could get the result by doing this: foo=: 3 : 0 data=. (0,(#|: 0 pick y)) $ <'' for_xyz. y do. data=. data, tomatrix 0 pick xyz end. data ) foo (< every i. 2 5);<<every i. 3 5 +--+--+--+--+--+ |0 |1 |2 |3 |4 | +--+--+--+--+--+ |5 |6 |7 |8 |9 | +--+--+--+--+--+ |0 |1 |2 |3 |4 | +--+--+--+--+--+ |5 |6 |7 |8 |9 | +--+--+--+--+--+ |10|11|12|13|14| +--+--+--+--+--+ So how do I get what I want without resorting to a for_ loop? Thanks. :) r/Alex ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
