I. PURPOSE
A general wavelet is not always a satisfying one, in terms of perpendicularity.
That’s why Mallat algo exists. With a method called Multi-Resolution Analysis( M
RA ),
we can get a better wavelet base from Shannon function: f(t) = sin(PI*t)/(PI*t).
In experiment I, we have just seen how to store a function and get a restor
ation of the original f(t). Here we will talk about a specific algorithm by Mallat
