Levenberg-Marquardt optimizer and new diagnostic terms available
Please view #21 for more details.
- Levenberg-Marquardt algorithm is now available.
Levenberg-Marquardt algorithm is one of the most famous minimization algorithms. The calculation of chi-squared and the packing of jacobian are different from the present optimization algorithms (DF, CG). Please view lmalg.pdf - More diagnostic terms in diagnos.h.
- calculate the overlap rate between the present Bn harmonics and the target harmonics
- compute a coil importance array (coil_importance in hdf5 file) for each coil
- Several bugs are fixed.
- add warnings about reset weights below machine precision
- fix nfp reset issue
- decompose Bn from coils only
- update ellipse example
