10组图论编程

说明：  Use of DFT or FFT with Matlab

This is the second part of Noonegative Matrix Factorization

基于时域有限差分法（FDTD），用MATLAB编程计算双球金纳米颗粒的局域电磁场增强(二维)的程序||2sphere2D.m(Base on FDTD ,local field enhancement of gold double sphere nanoparticles（2D）by Matlab || 2sphere2D.m)

说明：  提取远场图,提取参数后处理，可以完成多种数据处理的科学计算(extract farfield pattern)

两种滤波方法在导航上的应用，并且进行比较(Filter in the navigation on the two applications, and to compare)

重要是实现通过瑞利信道的QPSK的仿真，同时给出了其误码率的仿真(Important thing is to achieve through the Rayleigh channel QPSK simulation, while its error rate is given simulation)

gmdh神经网络的详细程序，demo是主程序源码。(gmdh detailed procedures for neural networks, demo is the main source.)

说明：  Remez滤波，BPSK复合基带信号仿真，载波生成器!(Designed to meet the following indicators, such as ripple linear phase FIR low-pass filter)

说明：  here i have attached the file of fdtd 1d sample coding

The audio processing program is used for recognition of digital audio source by alogrithm of HMM.
