I would like to try the Continuous Wavelet Transform to extract the features of non-linear and non stationary 1D signals. I can remove the noise and the trend so make them easier to analyze. I am not sure the CWT will work. To the purpose of trying it out I have downloaded the Rwave package. To my dismay, no example is provided for any of the functions making up such a package. The on-line documentation (so to speak) does not even describe the input file (vector) format. My signals are all in ascii format. They are made up of amplitude, time, phase which are all real numbers. I wonder if I can feed any of my signal to Rwave functions ??? I would appreciate seeing some usage example.
