Well, actually this would be a good example of when the Listable runs
amok, since this isn't giving the Log of the matrix
as one might expect. Another example along this line is
multiplication of matrices:
In[28]:= {{1,1},{1,0}} * {{1,1},{1,0}}
Out[28]= {{1, 1}, {1, 0}}
In[29]:= {{1,1},{1,0}} . {{1,1},{1,0}}
Out[29]= {{2, 1}, {1, 1}}
Still, the ability to thread an operation over lists can be pretty
handy.
Cheers,
Peter
