N dimensional ball 
N components: S=(S^{x},S^{y},S^{z},S^{u},...) Norm S=1 P(x)=r^{N1}.dr.sin^{N2}(a).da.sin^{N3}(b).db ... dp =r^{N1}.dr.(1z^{2})^{(N3)/2}.dz.(1y^{2})^{(N4)/2}.dy ... dw 
The Fast Linear Algorithm (FLA) uses the rejection method with a function consisting of n steps (see the figure and article for more details) 
1.  To use the Fast Linear Algorithm you must have :  


2.  AND you must have the tables in the file "ball.res". Two choices: . You can choose to download the file ball.res already done or make one with create_ball.out (.exe for windows), run it, and follow the instructions.
