  • GP_Algorithm2.0
    G-P算法计算关联维的 Matlab 程序 (升级版,mex函数,超快) ----------------------------------- 更新部分: 引入限制短暂分离参数,使该参数大于序列平均周期时,去除了同一轨道前后点的关联, 使 r 值较小时,ln r - ln C(r) 曲线接近线性(G-P method to calculate the correlation dimension of the Matlab program (upgrade version Files function, Ultrafast)----------------------------------- Update parts : the introduction of restrictions on temporary separation parameters so that the parameter is greater than the average cycle sequence, In addition to the same orbit around the point and makes a relatively small r, r ln- ln C (r) almost linear curve)
