说明：  优化软件包，MATLAB，应用于YALMIP(Optimization software package, MATLAB, used YALMIP)

IIR和FIR滤波器的设计，用脉冲响应不变法和双线性变换法设计IIR滤波器，用窗函数法设计了FIR滤波器。(IIR and FIR filter design, with the impulse response method and the bilinear transform IIR filter design using window function design of the FIR filter.)

matlab下将彩色图像装换为灰度图像的一个小程序(a small programm for convert the colour image to gray image using maltlab platform)

MATLAB最优化计算的学习资料，值得一读！！！(MATLAB optimization calculations of learning materials, worth reading! ! !)

计算时间序列样本熵，一种很有效的算法，依据算法步骤而编译(Calculate time series sample entropy)

加权平均法是DEM移动内插法的特例，是一种简化的逐点内插法。它是先以内插点为中心，确定一个取样窗口，然后计算落在窗口内的采样点的特征值的平均值，作为内插点的特征值的估值，(The weighted average method is a special case of the DEM mobile interpolation, a simplified point-by-point interpolation. It is the first interpolation point as the center, to determine a sample window, and then calculate the average of the characteristic values ​ ​ of the sample points falls within the window, the valuation of the points of the feature value as the interpolation,)

该程序是同步中的相位估计方法，该方法可以估计不同参数下的相位大小(The program is synchronized in phase estimation method which can estimate the parameters of the phases of different sizes)

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.)
