For what it is worth, here is the one liner that does this comparison:
a.minus(b).aggregate(Functions.MAX, Functions.ABS)
This gives you a value which is the magnitude of the largest absolute
difference between elements of matrix a and matrix b.
For vectors, you can economize a little on typing with this:
a.minus(b).norm(1)
This is the sum of the absolute values of the differences.
