pca_solve¶
- pydl.pydlspec2d.spec1d.pca_solve(newflux, newivar, maxiter=0, niter=10, nkeep=3, nreturn=None, verbose=False)[source]¶
Replacement for idlspec2d pca_solve.pro.
- Parameters
- newfluxarray-like
The input spectral flux, assumed to have a common wavelength and redshift system.
- newivararray-like
The inverse variance of the spectral flux.
- maxiter
int, optional Stop PCA+reject iterations after this number.
- niter
int, optional Stop PCA iterations after this number.
- nkeep
int, optional Number of PCA components to keep.
- nreturn
int, optional Number of PCA components to return, usually the same as
nkeep.- verbose
bool, optional If
True, print extra information.
- Returns
dictThe PCA solution.
