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.
