exactly. So I have a suggestion (maybe wrong): what about generating
floating point random matrices with a limited number of decimals ?
this way the loss of precision should be significantly reduced and we
should be able to reduce the tolerance thresholds to more decent
values. What do you think ? (we would do that only in the unit tests)
