DiagonalizableQ

When I cut and paste "DiagonalizableQ[{{0, 1}, {0, 0}}]"

>From the following, which can be found under Applications at
http://reference.wolfram.com/mathematica/ref/JordanDecomposition.html...

>> Test if a particular matrix is diagonalizable:
>> In[2]:= DiagonalizableQ[{{0, 1}, {0, 0}}]
>> Out[2]= False

I get... Out[2]= DiagonalizableQ[{{0, 1}, {0, 0}}] and not False

Can anyone give me some direction on using DiagonalizableQ?

Thanks!

Sincerely,

Jim
