i need a example code for Single-level discrete 2-D wavelet transform

since i am newbie to matlab i dont know how to start this project. obviously my project need feature extraction method which has involved in discrete wavelet transforms please help me answer this code

Say x is your signal and you’d like to do an n-level decomposition, using

[C, L] = wavedec(x, n, ‘db2’);

db2 is the wavelet you choose to decompose this signal x.

Better to check ref page. There are a lot more examples.
