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.

my problem is about function of wavelab toolbox of stanford university not in means of dyadic

Hi Nasim, Try and focus your question so that others can help you. 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.

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?
