Hi all, I am needing to create a wavelet Basis matrix such that f=Bw where f is the signal, B the basis matrix and, w the weight matrix. I am not concerned about w which I can easily obtain from most wavelet packages. Is there a package/ function that can create the B matrix (supposing it is a Haar wavelet for now, if it helps)? I have tried to look in WaveLab and Rice Wavelet toolbox (in Matlab) without much luck. If there is no package, it would be great if someone could point me in the general direction. Any help would be appreciated. Thanks, Sachin [[alternative HTML version deleted]]
