说明：  已知一组数据,如何用matlab画出它的概率密度分布图,给出具体程序 并且得出分布图后,如何对图进行积分,进而得到分布函数(Given a set of data, how to draw it with matlab probability density distribution maps, specific procedures are given and draw maps, how points on the graph, and then by distribution function)

说明：  绘制庞加莱截面图,在相空间中适当（要有利于观察系统的运动特征和变化，如截面不能与轨线相切，更不能包含轨线）选取一截面，在此截面上某一对共轭变量如x1和x.1取固定值，称此截面为Poincare截面，相空间的连续轨迹与Poincare截面的交点成为截点。(mapping Poincare section, in phase space appropriate (observation system should be beneficial to the movement and change, if not with the section line tangent track, rail lines not included) selected a cross section, in this section for a pair of conjugate variables such as x1 and X.1 from fixed value, stating that this section of the Poincare section, phase space for the track and Poincare sections of the intersection as intercept point.)

The remarkable advance in hydraulic and electrohydraulic power systems resulted in producing control valves of very short settling time. The rapid closure of hydraulic transmission lines leads to severe pressure surge. Thattached Simulink file is developed to evaluate the applicability of oleo-pneumatic accumulators for the protection against this phenomenon. A lumped parameter model was developed for the transmission line, assuming four lumps, considering the effect of line resistance, inertia and capacitance.
