Hi There, I tried to find a function in {waveslim} or {wavethresh} in order to reconstruct the decomposed signals. As far as I found there is no function in {waveslim} to reconstruct decomposed data. The function wr{wavethresh} reconstructs the results of wd function. Apart from its limitations ( for example the length of vector must be power of 2 ) it apparently doesn't work with the functions and objects in waveslim. What could help ? So many thanks for your any idea. Amir Safari --------------------------------- [[alternative HTML version deleted]]
