How can I tell to Maple that the sum:
Sum(v(n)*S(n),n=1..N)
where
S(n+1) = S(n) + xi(n+1)
can be rewritten as:
Sum(x(n)*xi(n),n=1..N)
where x(n)=Sum(v(k),k=n..N)
?
thanks
I try to deduce distribution fonction from a parametrized set of points with Maple.
At this stage I have a dataset define through a relationship like y=f(x), and I want to obtain the distribution of y points, given that x in [-A,A]. The theoretic formula is : F[Y](z) = P(y<z).
i.e. F[Y](z) = Int(delta[f(x)< z],x=-A..A);
and I use the piecewise Maple function to implement it ( Int(piecewise(f(x)< z,1,0),x=-A..A) ), but for Maple :
Int(piecewise(f(x)< z,1,0),x=-A..A) = piecewise(Int(f(x)< z, x=-A..A),1,0))
which is totally different !
has someone a sheet about percolation theory ?
I put a very simple one on my blog:
percolation
is it possible to implement a package so that the documentation and the help files will be automatically extracted from the sources?
