gives the inverse continuous wavelet transform of a ContinuousWaveletData object cwd.
gives the inverse transform using the wavelet wave.
gives the inverse transform from the wavelet coefficients specified by octvoc.
Details and Options
- InverseContinuousWaveletTransform computes the inverse transform of continuous forward transforms such as ContinuousWaveletTransform.
- The possible wavelets wave are the same as for ContinuousWaveletTransform.
- The default wave is Automatic, which is taken to be cwd["Wavelet"].
- The possible specifications for octvoc are the same as used by ContinuousWaveletData.
- The default octvoc is Automatic, which is taken to be cwd["WaveletIndex"].
- InverseContinuousWaveletTransform[cwd,wave,octvoc] computes the inverse transform using only the wavelet coefficients specified by octvoc; other coefficients are set to be zero.
