The module istkwave1 reconstructs a one-dimensional signal of size N from its one dimensional wavelet decomposition according to the J.L. Starck's algorithm [SBLP94] for a resolution np.
As long as the filters G and H verify G = 1 - H, we just need to add details and approximation for a resolution np in the frequency domain to get the signal back:
See documentation of module stkwave1 for more details.
