广义霍夫变换边缘提取代码，目标是针对图像中某一标识，进行识别和提取(Generalized Hough transform edge detection code, the goal is for the image of a logo, to identify and extract)

A code to solve a 2-D truss structure using FEM theorem (direct method). Each branch of the truss is considered as a 2-force member and the coordinates of the nodes in Cartesian system is needed. This code contains 3 functions: Truss_f, which is the main function to calculate stress, strain and force.M_properties22, which contains the mechanical properties of whole truss in a matrix P_condition22, which contains boundary condition and external forces in a matrix

matlab运行环境下可以用主成分分析对建模模型进行优化的程序(matlab runtime environment can be analyzed under the modeling procedures used to optimize the model main ingredient)

kalman filter for tracking

说明：  联通区域的标记 matlab 的bwlabel功能(matlab bwlabel )

说明：  Description : A simple simulation Model for DC DC step-down buck converter, the model allows measurments of output current/voltage, capacitor current, diode current. Ripples in each measurment can be observed very accurately using the scope

分别使用矩形窗和汉明窗函数设计一个线性相位FIR低通滤波器，使其逼近理想低通滤波器的频率特性。采用频率抽样法设计FIR数字低通滤波器滤波器。(Using rectangular window and hamming window function to design a linear phase FIR low-pass filter, the frequency characteristics of the ideal low-pass filter. Frequency sampling method is used to design FIR digital filter based on low-pass filter.)
