94 Chapter 4: IDL Wavelet Toolkit ReferenceArgumentsOrderA scalar that specifies the order number for the wavelet. The default is 4.ScalingOn output, contains a vector of double-precision scaling (father) coefficients.WaveletIoffJoffOn output, contains a vector of double-precision wavelet (mother) coefficients.On output, contains an integer that specifies the support offset for Scaling.On output, contains an integer that specifies the support offset for Wavelet.NoteIf none of the above arguments are present then the function will simply return theResult structure using the default Order.KeywordsNone.ReferenceCoefficients for orders 1–10 are from Daubechies, I., 1992: Ten Lectures onWavelets, SIAM, p. 198. Note that Daubechies has multiplied by Sqrt(2), and forsome orders the coefficients are reversed. Coefficients for orders 11–15 are fromhttp://www.isds.duke.edu/~brani/filters.html.Version History5.3 IntroducedWV_FN_SYMLETIDL Wavelet Toolkit
