Dead link and example #11

Closed Garfield2013 closed 1 year ago

Hi there,

Thank you for your interesting module :) I all new to wavelets but I'm trying to use it to smoothening data / denoising signals.

  1. FYI: This link here is dead: https://symmetronic.github.io/covid-19-dwt-analysis/
  2. How do I prune coefficients which I would like to remove - so I can adjust the smoothening level of the signal?

const coeffs = wt.wavedec(points, waveletType);

const prunedCoeffs = ??

const smoothedData = wt.waverec(prunedCoeffs, waveletType);

Thank you so much!

Hi @Garfield2013,

sorry for my late reply!

  1. Thank you for the notice about the dead link. I just removed it.
  2. I also added a note to the README.md that I'm currently not able to add any new features or documentation due to limited time.

Best wishes!
