Hi,
I receive a length error while using %. and I don't know why.M=. |: 1 418 398 1639 3430 1184,.1 580 572 1197 3044 1309,.1 622 596 1347 3531 1155
y=. 579 496 510
y %. M
|length error
| y %. M
Is it because the columns of the matrix are not linearly independent ?
If so, how can I check if they are in a non-square matrix ?
Thanks a lot Philippe Nadeau ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
