| Abstract: | The iterated function systems (it is called IFS for short) theory and the random iteration algorithm are expounded. By the theoretical analysis, the method by which the boundary of a class attractors of IFS using two affine maps can be evaluated is given out. The algorithm of determining the Lyapunov exponent and the correlation dimension of the attractors of IFS is introduced. Utilizing the computer simulated a class two-dimensional, three-dimensional attractors of IFS, the boundary, the Lyapunov exponent and the correlation dimension of the attractors of IFS are calculated, and the dynamic characteristics of the attractors of IFS are analyzed. |
