Summary

Description
English: Barnsley's fern illustrates the use of affine translations in an iterated function system (IFS) to create a fractal. In Table III.3 of Michael Barnsley's book, the IFS code for the four affine transformations for the Barnsley leaf is given as a table of values for the coefficients a, b, c, and d, the constants e and f and the probability percentage factor of p as follows:
   a     b     c     d       e      f      p
   0     0     0     .16     0      0     .01
  .85   .04  -.04    .85     0     1.6    .85
  .2   -.26   .23    .22     0     1.6    .07
 -.15   .28   .26    .24     0      .44   .07
