摘要
详细地研究了计算混沌映射不变分布的几种数值方法.结果表明,公式法适用于类似抛物线映射简单类的情况;直方图法适用于统计样本较大的情况;特征向量法适用于统计样本较少,但转移概率已知的情况。以logistic map混沌映射为例作了仿真,计算机模拟结果与理论分析结果相符。
The three methods of calcucation invariant probability distribution for chaotic map are investigated in detail. The results indieate that the formula method fit for the map is simple,for example,Parabolic map,the histogram method is fit for the situation that the number of statistical sample is large,and the feature vector method fit for the transferred\|probability matrix is derived.A representative logistic\|map is simulated,and these results are in agreement with those of theoretic analysis.
