Hi,
I'm working on making the linear package standalone. The methods that perform
precondition checks for matrix operations throw exceptions (See below). An
option would be return a boolean instead. Obviously I would love it if CM
adopts the code at some point, so I want to check whether changing the
interface is going to kill kittens.
Cheers,
