求解一维热方程。空间方向采用四阶差分格式，时间方向采用bvm法(Solving one-dimensional heat equation. Spatial orientation difference scheme with fourth order, the time direction by bvm method)

说明：  在数字信号处理，采用滑动平均的方法消除噪声(In digital signal processing, using moving average method to eliminate noise)

JDO的学习资料，自己整理了一本分，是值得学习的东西(JDO' s learning materials, their order a part, is something to be learned)

Achievo ATK 是一个以提升开发速度为其核心目标的业务框架。该框架的所有部分都以减少应用程序代码为目标。它没有提供大量工具类以实现广泛的功能，而是提供了一个通用 框架来减少代码。所有新增特性都经过慎重考虑 — 只有它们在某些地方能够降低开发时间才添加。 Achievo ATK 新特性的添加在某种程度上来说是一种演进式开发。没有专门负责开发新特性的团队；而是基于使用该框架的应用程序的要求来对其进行扩展。 (Achievo ATK is an upgrade to speed the development of the core objectives of the operational framework. The framework All parts are to reduce application code as a target. It did not provide a large number of tools to achieve the broad category of the function, but to provide a general framework to reduce code. All these new properties are the result of careful consideration- they are only in certain areas to reduce the development time to add. Achievo ATK new properties added to a certain extent, this is an evolutionary development. Not specifically responsible for the development of new properties team; It is based on the use of the framework of the application's requirements for its expansion.)

电磁场数值计算的作业代码和文档，绘制了一个立方体空间中电磁场变化情况(Job electromagnetic field numerical calculation code and documentation, draw a cube space electromagnetic field changes)

Formats tracker data as KML output.

快速eemd算法，收敛速度与传统eemd相比有很大改进(EMD is a nonlinear and nonstationary time domain decomposition method. It is an adaptive, data-driven algorithm that decomposes a time series into multiple empirical modes, known as intrinsic mode functions (IMFs).)

OFDM系统信道估计算法MATLAB实现，基于信噪比和误码率对LS、MMSE算法进行性能对比。(OFDM channel estimation algorithm MATLAB system, based on the signal to noise ratio and bit error rate performance comparison of LS, MMSE algorithm.)

S函数编写指导，可以用来编写matlab的simulink中S函数，很实用(S-Funtion Study)
