说明：  本程序为带有偏微分的PID控制程序，很好的解决了传统PID控制的不足。(This program is the PID control with partial program, a good solution to the shortage of traditional PID control.)

leach algorithm for wsn

从曲线图采样数据拟合曲线，采用不同的插值方法，得到不同的插值曲线(Sampling data from the curve fitting curve)

一本数值分析英文书籍，各种方法均配有相应的程序，用matlab，fortran等编写，值得一看(A numerical analysis of the English books, various methods are equipped with the appropriate procedures, using matlab, fortran, etc., worth a visit)

说明：  空间信号的波达方向（Direction of Arrival，简称DOA）估计作为阵列信号处理研究的一个主要课题，在近些年来越来越得到大量的关注和研究。它可实现对空间中信源信号的准确的角度估计，实现信源方位等参数的具体精确检测，并且还具有很高的分辨力。这些特性使得DOA估计在声呐、通信及雷达等多种领域具有广阔的应用和发展前景。此程序为面阵中二维角度估计算法程序。(direction of arrival,usually called DOA,has been an important subject recently.This program contains unitary esprit)

本资源是关于matlab编程技巧的介绍，可以作为教材的辅助资料，提高编程水平。(This resource is introduced on the matlab programming techniques can be used as supplementary teaching materials to improve the level of programming.)

说明：  利用matlab解海伦方程并画出电流分布图(solutions using Matlab and paint Helen equation current distribution plan)

计算信号的魏格纳分布。 用法见函数说明。(Calculate the signal Wigner. Usage See function description.)

A cyclic redundancy check (CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to raw data.
