Hello everybody, I am using J801 under Ubuntu. Here is a behaviour I do not understand:
mat=:i.2 3 r90=:|."1@:|:"2 r90^:0 mat 0 1 2 3 4 5 r90^:1 mat 3 0 4 1 5 2 r90^:2 mat 5 4 3 2 1 0 So far, so good. But: r90^:(i.3) mat 0 1 2 3 4 5 0 0 0 3 0 0 4 1 0 5 2 0 5 4 3 2 1 0 0 0 0 Why the additional row of zeros? Thanks for any hint, Francesco ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
