Plot-Vdp-Oscillator

涉及机械土木工程的常用刚架结构的计算，给出计算实例及matlab源程序，是提高工程设计方法的有效手段(Mechanical Engineering involves the calculation of a common frame structure, a numerical example and the matlab source code is to improve the engineering design method of an effective means of)

交通分布中的无约束重力模型，matlab程序(A matlab program of unconstrained gravity model in traffic distribution.)

Single-level discrete 1-D wavelet transform

说明：  有偏卡尔曼滤波器可以用来消除无线定位中的非视距误差,本程序加入了非视距检测模块，对于NLOS使用有偏卡尔曼滤波，对于LOS使用标准卡尔曼滤波(Biased Kalman filter can be used to eliminate the wireless location in NLOS error, the program joined the non-line-detection module, for use NLOS biased Kalman filter, using the standard Kalman filter for the LOS)

matlab code for Learning the Extended Kalman Filter

基于matlab的卡尔曼滤波，内容为工具箱及案例代码程序(Matlab-based Kalman filtering, content toolkit and case code program)

MATLAB 仿真一个光伏升压变流器，从12V升到大概300多伏吧，很基本的仿真模型。(matlab PV invertor)

直方图是用面积表示各组频数的多少，矩形的高度表示每一组的频数或频率，宽度则表示各组的组距，因此其高度与宽度均有意义。 程序提取了很多直方图所需要的参数特征，如均值、方差、偏度、峰度、能量和熵。 (Histogram is that each group size the number of frequency, the height of the rectangular frequency of each group said that the number or frequency, the width of that group from each group, so the significance of height and width of both. Extraction procedures need a lot of parameters histogram features, such as mean, variance, skewness, kurtosis, energy and entropy.)

全MATLAB仿真的程序，没用到SIMULINK(MATLAB simulation of the whole procedure, no use to SIMULINK)

用matlab求二维凸包，并求出二维凸包的面积(Using matlab to calculate the two-dimensional convex hull, and find the two-dimensional convex hull area)
