Subject: sphere coordinates

I'm trying to get a matrix that includes the coordinates that are in a sphere. These coordinates are chosen random. This is the script now:



for i=1:N
    if A(i)>R^(2)


The idea is that i create a 3 by N matrix with coordinates that are in a 4x4 box with. When the coordinates are squared and added they should not be bigger than 2^2=4. When it is bigger than 4 the column should be erased out of the random matrix c.

But it doesn't work. Does anybody know how I have to do this
