一个 三维fdtd的matlab源代码(Three-dimensional fdtd the matlab source code)

Matlab based wireless sensor network code for hetrogeneous application in Airports. This is based on clustering of nodes.

fit_ML_normal - Maximum Likelihood fit of the laplace distribution of i.i.d. samples!. Given the samples of a laplace distribution, the PDF parameter is found fits data to the probability of the form: p(x) = 1/(2*b)*exp(-abs(x-u)/b) with parameters: u,b format: result = fit_ML_laplace( x,hAx ) input: x - vector, samples with laplace distribution to be parameterized hAx - handle of an axis, on which the fitted distribution is plotted if h is given empty, a figure is created. output: result - structure with the fields u,b - fitted parameters CRB_b - Cram?r-Rao Bound for the estimator value RMS - RMS error of the estimation type - ML

说明：  使用matlab模拟迈克尔逊干涉等厚、等倾干涉图样(Simulation of Michelson interference equal thickness interference pattern with MATLAB)

说明：  龚纯主编的“matlab语言常用算法程序集”的第四章源代码(Gong pure edited matlab language commonly used algorithm for assembly, &quot the fourth chapter of source code)

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!)

pure aloha 和slotted aloha算法的 matlab代码。结果显示了两种算法吞吐量的对比，通过修改标签数也可以得出吞吐量的变化值。 纯ALOHA协议(Pure ALOHA) 当传输点有数据需要传送的时候，它会向立即向通讯频道传送。 接收点在收到数据后，会ACK传输点。 如果接收的数据有错误，接收点会向传输点发送NACK。 当网络上的两个传输点同时向频道传输数据的时候，会发生冲突，这种情况下，两个点都停止一段时间后，再次尝试传送。 因为有太多的传输冲突.(pure aloha and slotted aloha algorithm matlab code. The results show the comparison of the two algorithms throughput, by modifying the number of labels can also come to change the value of the throughput. Pure ALOHA protocol (Pure ALOHA) When the transfer point has data to transmit, when it would have to immediately transfer to the communications channel. After receiving the data reception point will ACK transmission points. If the received data has an error, the receiver sends NACK point to point transmission. After transmission when two points on the network at the same time to the channel to transmit data, it will conflict, in this case, two points are stopped for some time, try the transfer again. Because there are too many transmission conflict.)

本程序是一个直接序列扩频仿真，开发环境时在matlab/simulink下进行的，程序简单易懂( This program is a direct sequence spread spectrum simulation, the development environment in matlab/simulink conducted the program easy to understand)

给定全息图恢复波前强度图，通过GS算法实现(The algorithm for restoring the wavefront intensity of holograms is realized by GS algorithm.)

一个很好的matlab中文帮助文档，希望对学matlab的人有所帮助(A very good Chinese matlab help document, in the hope that people learn matlab help)
