Ifs

Function: ifs ([<r1>, ..., <rm>], [<A1>, ..., <Am>], [[<x1>, <y1>], ..., [<xm>, <ym>]], [<x0>, <y0>], <n>, ..., options, ...); Implements the Iterated Function System method. This method is similar to the method described in the function chaosgame, but instead of shrinking the segment from the current point to the randomly chosen point, the 2 components of that segment will be multiplied by the 2 by 2 matrix <Ai> that corresponds to the point chosen randomly.

The random choice of one of the <m> attractive points can be made with a non-uniform probability distribution defined by the weights <r1>,...,<rm>. Those weights are given in cumulative form; for instance if there are 3 points with probabilities 0.2, 0.5 and 0.3, the weights <r1>, <r2> and <r3> could be 2, 7 and 10.
