Right. I tend to like self-describing names also good. In french (you've rightly spotted a non-native speaker...), an "operator" is not necessarily linear, and I think same goes to english terminology (could you confirm please). So a linear operator is not exactly identical to an operator. However,

OK Phil, I'm just worried about naming consistency. So should I drop "Linear" everywhere? Only in exception names (where I agree, it's not that important)? Thanks, Sébastien 2011/10/2 Phil Steitz : > On 10/1/11 9:42 PM, Sébastien Brisard wrote: >> My mistake! I was convinced we already had >>   -

Hello, I need to be able to throw an exception when an iterative linear solver detects that a RealLinearOperator is singular. I would propose to implement a SingularLinearOperatorException. Then, since RealMatrix is derived from RealLinearOperator, it would be logical to have SingularMatrixExceptio
