这是我们非线性课程的一次作业，有分岔图，蛛网图，庞加莱截面，希望对大家有用。,This is our first non-linear operation of the curriculum, there is bifurcation diagram, spider diagram, Poincare section, in the hope that useful to everyone.

用matlab实现的非线性动态范围调整的算法，供大家参考-Algorithm matlab achieve nonlinear dynamic range adjustment, for your reference
