a.transposed is just a view of the original matrix. Even when I 
tried to do a raw for loop I ran into issues because modifying 
the original a in any way caused all the calculations to be wrong.

Honestly, it's kind of rare that I would do an element-wise 
multiplication of a matrix and its transpose.
