Do you know what dyadic means? You need to look it up (e.g., http://www.thefreedictionary.com/dyadic), because you are making a fool of yourself asking such a question. All wavelet transforms are dyadic.

Which function of WaveLab are you talking about? If you present your question with reference to a specific function and provide a small MATLAB example of the difficulty you are having, you have the best chance of getting targeted help. Wayne

thanks for reply I have a 2D signal. I want get wt(x(t)) and wt(y(t)) (wavelet transform of signal) in dyadic scale level j(detail signal). how I use function dyad2 in wavelab ? does first input argument of this function is j in my problem? and is the output of this function is answer of my problem? if yes how I set type of wavelet(e.g haar)? how can I found help or example of using function of this toolbox? |
