Hi Can anyone help me with this problem. I am trying to create an entropy production diagram from the fig tree fractal. the formula for delta S (entropy) = X{n+1}*(X{n+1})/X{n}*(1-X{n}). I derived this formula from the Xnext formula and substituted that into the delta S formula of (lamda)*(change in flow, which is the same as X{n+1}-X{n}). Entropic forces create new flows (lamda or parameter r in some books) can be viewed as an entropic force). What the program needs to do is take out the repetitive points say for lamda (or parameter r) =3.5, x equals 0.875, 0.825, 0.5011, 0.3828. I was wondering if this could be done easily, can anyone help. kindest gavin
