these are matlab files in relation to RK4

将COMTRADE格式的数据转换成为真实的电气量值，并绘制波形(COMTRADE format of the data will be converted into actual electrical value, and draw the waveform)

本文件是用matlab编写的俄罗斯方块，还挺好玩的哦(This document is written using matlab Tetris kinda fun!)

本例用五点差分法求解一个二阶偏微分方程，其间用Jacobi迭代求解(This example uses a five-point difference method for solving second order partial differential equations, during which the Jacobi iterative)

广义最小方差自校正控制：在求解控制律的性能指标中引入对控制量的加权项，限制控制作用中的剧烈变化。(Generalized minimum variance self-tuning control: control the amount of weighted items, solving the performance of the control law introduced to limit the dramatic changes in the control action.)

融合程序,matlab的源代码。内含两个程序。(Fusion program, Matlab source code. Contains two procedures.)

matlab开发GUI地震数据显示工具，可以作为地震处理人员学习地震处理的起点。matlab是基于矢量运算，而地震剖面就是一个矩阵。用matlab来处理地震数据，用于学习研究地震处理的方方棉面，实在是方便实用。(matlab seismic data show the development of GUI tools can be used as seismic processing, seismic processing to study the starting point. matlab is based on the vector operation, and the seismic profile is a matrix. Using matlab to handle seismic data for the study of seismic processing Fangfang cotton face, it is convenient and practical.)

ESTIMATION OF AIRCRAFT TRAJECTORY FROM ITS MOTION USING KALMAN TRACKING FILTER

用于学习软判决解调算法,文件中包含用于算法描述的文献,以及对应matlab代码,支持PSK,QPSK,16-QAM,64-QAM四种调制方式(Demodulation algorithm for learning soft decision, contained in the file for the algorithm described in the literature, as well as the corresponding matlab code support PSK, QPSK, 16-QAM, 64-QAM four modulation)

主要讲述了指北方位平台式惯导的解算，有详细的语句解释(Mainly refers to the northern bit about the INS' s Solution Platform, a detailed statement to explain)
