gives the scaling function for the symbolic wavelet wave evaluated at x.
gives the scaling function as a pure function.
Details and Options
- The scaling function satisfies the recursion equation , where are the lowpass filter coefficients.
- WaveletPhi[wave,x,"Dual"] gives the dual scaling function for biorthogonal wavelets such as BiorthogonalSplineWavelet and ReverseBiorthogonalSplineWavelet.
- The dual scaling function satisfies the recursion equation , where are the dual lowpass filter coefficients.
- The following options can be used:
MaxRecursion 8 number of recursive iterations to use WorkingPrecision MachinePrecision precision to use in internal computations
