说明：  对心音信号实现平均周期图法功率谱估计的matlab程序(PSD bartlett matlab)

此程序实现一个模拟的雷达PPI显示界面，能显示雷达站的相关信息(this program produces a interpace about radar PPI, it can display radar station information)

三相电源的整流逆变，在某一时间点并网投入运行的一份仿真。(A simulation of three - phase power supply connected to the grid at a certain time.)

海明加权的天线方向图，使用matlab 调试过，对研究雷达天线的同志很有帮助。(Hamming weighted antenna pattern, use the debug matlab, and the study of the radar antenna comrades helpful.)

使用案例讲解了matlab中的随机数生成，有源代码程序(Generating random Numbers)

In this document has been introduced comprehensively how to solve different partial differential equations .Everbody can solve Heat Conduction Equation, Helmholtz Equation, Laplace Equation and Wave Equation for different initial and boundary conditions. This document is elemantary of to understand how to solve partial differential equations with the aid of a porgramming language.

设计一个数字FIR低通滤波器，其技术指标如下：Wp=0.2 Rp=0.25 Ws=0.3 As=50(Design a digital FIR low-pass filter, the technical indicators are as follows: Wp = 0.2 Rp = 0.25 Ws = 0.3 As = 50)

采用Matlab工具箱函数建立神经网络，对一些基本的神经网络参数进行了说明，深入了解参考Matlab帮助文档。 (Using Matlab toolbox functions to establish neural networks, some of the basic neural network parameters are described to understand the reference to Matlab help documentation.)

说明：  用sa进行光谱图像的特征提取的matlab程序，该算法比用其他方法在性能方面高%15(with spectral images of the Matlab feature extraction procedure, the algorithm than other methods in high-performance)
