Hi,

Power[] had nothig to do with Dot[] you mean
Dot[m,m] and not Power[m,2] and you should
write this ...

| Hi,
|
| Just trying to get to grips with Mathematica and 
matrices.  Why is it when I
| enter :-
| {0, 0, 0}, {1, -1, -1}, {-1, 1, 1}}^2
|
| then Mathematica returns :-
|
| {{0, 0, 0}, {1, 1, 1}, {1, 1, 1}}
|
| and not {{0,0,0},{0,0,0},{0,0,0}} (the actual 
square of the matrix) as I'd
| have expected?
|
| Is it treating what I entered as separate 
vectors or something, and not  an
| actual matrix?
|
| Thanks
|
