calculate matching covmat #32

Closed RoyStegeman closed 2 years ago

RoyStegeman commented 2 years ago

@Radonirinaunimi the covmat seems to contain as many negative as positive entries?

Does this happen to all the datasets or only a subset of them?

I guess I can merge this branch to the matching-grids branch now #29 ?

RoyStegeman commented 2 years ago

Sure
