This routine draws Barnsley s fern, The transformations for the fern are each in the form T(x,y = (a*x+b*y+e, c*x+d*y+f). If the probability that a particular transformation T is selected is p, you can characterize each transformation by providing the values of a,b,c,d,e,f, and p, in that order. -This routine draws Barnsley s fern, The transformations for the fern are each in the form T (x, y = (a* x+ B* y+ E, c* x+ D* y+ F).
