Lorenz说：“在巴西的蝴蝶拍打翅膀会引发德克萨斯州的一场龙卷风吗？”，就是“蝴蝶效应”，是由三维常微分方程组描述的，本算法用来计算蝴蝶效应("Does a butterfly flapping its wings in Brazil trigger a tornado in Texas?" Lorenz said" The butterfly effect is described by the three-dimensional ordinary differential equations. This algorithm is used to calculate the butterfly effec)

说明：  该程序是日本人用matlab写出来的提取pitch的，效果很好，唯一的缺点是算的太慢(The program is written in Japanese with matlab the extraction of the pitch, well, the only drawback is that the slow count)
