How to use wfilters in MATLAB

Hello ,

I want to implement Discrete Wavelet Transformation using 'Haar' criteria. I found the relevant document also on mathworks but somehow I did nou understand how to implement it for my data set.

http://www.mathworks.co.uk/help/wavelet/ref/wfilters.html

I was reading the above documentation. I would be gratefull if someone can tell me how to implement it on a column vector.

Thanks

sorry for the trouble but I just saw that this function is in wavelet transformation toolbox which is not installed in my machine.

Sorry for the problem again .

Can I delete the question?
