This file include many matlab excercise, you can download and using file .m to examine your matlab s skill. Thanks for see!

I am simply extracting three types of features from the wavelet transform coefficients, these include: energy, variance and waveform length. You can modify and extract any types of features as you need. ** You need the wavelet toolbox to run this code.
