Optimize memory usage in `dofisher`
This PR improves memory usage of dofisher
by avoiding allocating the Sig
matrix during Fisher computation.
This build, which comprehends the improved trace computation (!7 (merged)), has been tested assuming nside=16
, a mask with fsky~30%
and using dofisher_QU
.
In particular, the output Fisher matrix from the master branch and this one are identical.
