How to extract Principal Components as numpy arrays?

[kcnguyen3191]

Hi All,

I have been trying to see if I can extract the time series of the principal components as numpy arrays of time series. I know components_ will give me the time series, but they are in FDataGrid. I tried to use .to_numpy() function in this document, but it just seems to wrap numpy array around FDataGrid data type variable. Is there a way to this?

Thanks!

You can find the array containing the values of the function in the data_matrix attribute of an FDataGrid, as explained here. Maybe that is what you want?

Yes, this is exactly what I want. Thank you!
