Logistic映射与奇异吸引子 一、logistic映射---通向混沌的道路 混沌系统，由于其行为的复杂性，往往认为其动态特性（运动方程）也一定非常复杂，事实并非如此，一个参量很少、动态特性非常简单的系统有时也能够产生混沌现象，以一维虫口模型为例，假设某一区域内的现有虫口数为yn，(logistic实现6蛛网迭代)

roots -Polynomial roots Syntax r = roots(c) Description r = roots(c) returns a column vector whose elements are the roots of the polynomial c. Row vector c contains the coefficients of a polynomial, ordered in descending powers. If c has n+1 components, the polynomial it represents is . Tips Note the relationship of this function to p = poly(r), which returns a row vector whose elements are the coefficients of the polynomial. For vectors,roots and poly are inverse functions of each other, up to ordering, scaling, and roundoff error.
