i d0nt know how to apply the dyadic wavelet transform on the image and get the corresponding results...

can anybody help me by writing few lines of code by taking any image

[LL,HH]=dwt2(inputImage,'haar');

this i know in case of discrete wavelet transform but in dyadic wavelet i dont know the function which can divide the input image into 2 parts

part 1======approxiamtion (low pass filter)
