Reconstruction from joint time-frequency coefficients #13

Closed lostanlen closed 9 years ago

lostanlen commented 9 years ago

This PR from the reconstruction branch provides the ability to approximately reconstruct a signal from its averaged joint time-frequency coefficients. It also brings a function sc_invert for exact inversion of any multi-variable wavelet transform. It fixes some important bugs related to ranges and sibling inequalities ; dual filters ; Gammatone wavelets ; backpropagation ; and subscripted reference.
