Re: [eigen] LU test fails

[ Thread Index | Date Index | More Archives ]


Thanks for your report.
Don't worry about this failure: if it succeeds most of the time, then
you can consider that it is just noise. The truth is that in this
particular test I should relax the == requirement a little bit.

About running the tests:
cd test

you can run a particular test directly, there are command line options
(pass "help" or anything else on the cmd line).
