Gilles commented on MATH-1004:
------------------------------
bq. I would prefer adding it as MatrixUtils.inverse(DiagonalMatrix)
Why?
Note that the "blockInverse" operates on any base type that can provide an
inverse. It's (sort-of) higher-level. Here the implementation is specific to
the actual type.
