Hi,
Could someone tell me how to extract a sub-matrice from another one?
I have  (omitting brakets):
          0 0 0 0 0
M =   1 2 3 4 5
          6 7 8 9 10
I want to suppress the first line (zeros).
I look into the programming book but it is not working.
mat N = M[2...]
And keep getting :
M not found.
I've also tried
mat N = M[2,*]
Thanks for helping.
Amadou.
