Lorenz系统的Poincare截面计算方法。用于分析转子点映射特性(Poincare cross-section of the Lorenz system calculation. Used to analyze the characteristics of rotor-point mapping)

it contains many classic Test Problems for Unconstrained Optimization such as camel6,treccani,goldstein,branin, shubert1,Ackley,dejong,dejong1,dejong2, dpower,rastrigin,Griewangk,Schwefel, rosenbrock2 and step. the package have the contour and mesh figures of these problem. it also give m files of these problems,and you can easily get your view of figures.(it contains many classic for Test Problems Unconstrained Optimization such as camel6. treccani, goldstein, branin, shubert1, Ackley. dejong, dejong1, dejong2, dpower, rastrigin.
