龙贝格算法的mathlab实现源代码，一般在计算方法课上使用(Romberg algorithm mathlab implementation source code, generally used in the calculation method of class)

说明：  用matlab算法实现的平方根算法 用于数值分析中平方根发求解线性方程(Matlab algorithm using the square root algorithm for the numerical analysis of the square root of hair for solving linear equations)

说明：  matlab需需要的M文件，可以在里面调用买很好用没人穿就是，很可惜(files are needed by MATLAB)

图书电扫阵列-matlab建模与仿真，第三章编码(codes of book chapter3)

利用bp系统预测北京98-05公交客运量(Bp system in predicting the use of public transportation passenger Beijing 98-05)

this file consists of the turbo code in the AWGN channel. the simulation will nearly take 20 min to simulate but it will produce an excellent output with reaching the Shannon s limit exactly at 0.5db.

说明：  读取地震数据的道头字并画出剖面图, 没有读出所有的道头，只读取了几个角为重要的(read headers of seismic data and draw the profile)

These are MATLAB codes for implementing Chebyshev-Type 1 Bandpass and Bandstop filters.

水声通信面临的最困难的问题是多途干扰,其中自多途引起接收信号的幅度衰落,互多途引起接收信号的码间干扰,再加上海洋环境的高噪声背景、低的载波频率、极为有限的带宽以及传输条件的时间—空间—频率变化特性,使得通信过程十分困难。此外，水声通信试验的成本高，难度大，也为水声通信研究带来挑战。 本软件对水声信道的仿真研究很有帮助，可以产生声线图，冲激响应，声速图等仿真文件，结合Matlab画图工具绘制图像，对水声信道的模拟仿真很有帮助。(The most difficult problem faced by underwater acoustic communication is multi-path interference, which since multipath fading caused by the magnitude of the received signal, and mutual inter-symbol interference caused by multipath signal reception, plus the marine environment of high background noise, low carrier frequency , very limited bandwidth and transmission conditions of time- space- frequency characteristic such that the communication process is very difficult. In addition, the high cost of underwater acoustic communication experiment, difficult, and challenges for the study of underwater acoustic communication. This software is useful for simulation study of underwater acoustic channel can produce sound chart, impulse response, sound velocity diagrams simulation files, combined with Matlab drawing tools to draw the image of underwater acoustic channel simulation helpful.)
