## pca_start_evectors()


Calculate the starting eigenvectors for the high-frequency PCA routine.


Usage

``` python
pca_start_evectors(
    X,
    k=None,
    u=None,
    quiet=True,
)
```


Function is being questioned. Will probably be moved inside [pca_high_freq](pca_high_freq.md#hfpca.pca_high_freq).
