LDLt decomposition?

[DrD]

ALL similar matrix commands have the same requirement: ADDROW(), DELROW(), SWAPROW(), etc., all have the same CAS requirement in order to work on the HC and virtual calc. They seem to work ok on the Android app. I sent a bug report in, but, maybe this is intended behavior? If the command names were in lower case, it would serve as a hint that they need CAS handling.
