Typically I would define a block diagonal matrix as a square matrix as
the Wikipedia does. However, it might be nice to side with Matlab
since there may be circumstances where one needs a more general block
diagonal matrix than a square one.
Personally, if it is just as efficient algorithmically, I would
side with the more general definition as Matlab does. Thanks again
for all of this.
