PSO算法最小化配网建设成本，希望对初学者有用(PSO algorithm to minimize the cost of distribution network construction)

是给一个有限长序列补零（可以在前面或后面补零），用Matlab画图比较原序列，前补零序列以及后补零序列(very good)

《MATLAB控制系统仿真与实例详解》的附书光盘文件，包含各章的实例代码。(" MATLAB and Control System Simulation example explanation" of the CD-ROM with the book file, each chapter contains examples of code.)

《MATLAB工程应用书库：MATLAB小波分析（第2版）》以最新版MATLAB R2011a为平台编写。从信号处理的角度阐述小波分析的基本原理及其应用。(The MATLAB application stacks: MATLAB wavelet analysis (second edition))

用matlab读取.dxf文件。本站原有代码dxf2coord_20.m中对于圆弧只能读出其圆心坐标及半径，缺少圆弧起始角及终止角，并不能在应用中实际用起来。修改后可以读出圆弧的起始角和终止角(the script can offer start angle and end angle of an arc,which are unable to access in an earlier script dxf2coord_20.m 。)

用双线性变换法设计IIR数字滤波器 滤波就是将外界干扰的不需要的频率滤除掉，一面影响要测试数据的结果。比如如果是心电波的话，如果这是外界有很大的噪声干扰，滤波就是把不必要的信号给抑制掉，以便对心跳的正常测试。通过图比较，滤波后的明显比之前的要平滑，就是滤去干扰噪声的结果。采样间隔对实验有影响，取的过大会导致频率混叠。(Bilinear transformation method using digital filter IIR filter design is to outside interference filter out unwanted frequencies, while the impact to test data results. For example, if it is so heart waves, if this is a great noise outside interference, filtering is unnecessary signal out to the curb in order to test the normal heartbeat. Through chart comparison, after filtering than before to smooth the noise interference is the result of least squares. Sampling interval of the experiment affect take-off frequency of the General Assembly leading to aliasing.)
