Hi List, We now have some real unit-tests (more to come). They already allowed to discover (and fix) several grave bugs. Some were compilation bugs. Another one, introduced by me when I modified Michael's loop unroller, caused the first entry of matrices to be copied twice. It then causes errors in e.g. operator +=. This is now fixed, and the removal of the redundant copy also improves performance. The performance chart is now: Eigen1: 8.2s Tvmet: 6.1s Eigen2: 5.0s If someone wants to help, a simple TODO item consists in letting the test app take a command-line argument --seed=value, which would allow to easily reproduce test failures. I think that Qt can help parsing the command-line. Cheers, Benoit
