Haar wavelet transform using TSpectrumTransform class

[dasdebasish]

Hello ,
Is there anyway to see how one can use haar wavelet using TSpectrum class?
I am looking for if anyone has tried that function?
regards
Debasish.

Dear Debasish,

Thanks for the interesting post and welcome to the ROOT community!
No, as far as I know, nobody tried, but clearly I may be wrong.

Cheers,

I added these lines on root > .x Transform.C code in TSpectrumTransform link,
Trying to find out if thats how it should be, any suggestions?

  TSpectrumTransform* Transformer1dimHaar = new TSpectrumTransform(4096);
  Transformer1dimHaar->SetTransformType(TSpectrumTransform::kTransformHaar,0);
  Transformer1dimHaar->SetDirection(Transformer1dimHaar->kTransformForward); 
  Transformer1dimHaar->Transform(source,destinhaar);
  TH1F* hresultHaar = new TH1F("hresultHaar","Haar Transform of input",nbins,xmin,xmax);
  for (Int_t i = 0; i < nbins; i++)hresultHaar->SetBinContent (i + 1, destinhaar[i]);

If anyone has tried will be eager to discuss
