- TrainSum.idwt(dim, coeffs)
Inverse wavelet transformation matrix as a quantics tensor train. Coeffs define the low-pass filter coefficients defining the wavelet. The wavelet is constructed exact. Application of the train results in [approximations | details] coefficients. Note: no padding used, thus the extremes might differ from pywt.
- Parameters:
dim (Dimension)
coeffs (Sequence[float])
- Return type:
