right, so, i got this question,

= |0 1 0 |
Let A = |0 0 1 |
= |0 0 0 |

Determine the dimension of the subspace
V={B E M3x3 ® :BA=AB}

and i got the answer as this

|0 1 0| |0 0 1|
|0 0 1|, |0 0 0|
|0 0 0| |0 0 0|

But the answer was supposed to be this, but plus extra one matrix, which is

|1 0 0|
|0 1 0|
|0 0 1|

how do i get to that ?

it's sunday, and i can't possibly ask my lecturer today, so, yeah... =)
