Phil Steitz commented on MATH-1004:
-----------------------------------
+1 to Thomas' suggestion to have DiagonalMatrix directly implement inverse
(with configurable singularity threshold).
Probably should be a separate ticket, but +1 as well to MatrixUtils.inverse.
Question there is what is best generic use decomp solver for inversion.
