费聂耳衍射成像的模拟，采用透镜成像原理，有效地利用fft(simulation of the diffraction，based on the optical lens and the theory of fft)

说明：  仿真通过利用虚拟信道模型而产生瑞利衰落信道(rayleigh)

读取Yokogawa DL 750, DL 1600 系列 与 DL 7440 示波器的数据. 特点：允许多个通道（trace）的输入，如： [x(:,1:4),x(:,5)]=wvfreadb_moreinput(filename, 1, [1,2,3,4], 1) (loads YT-waveform data from*.wvf file saved by Yokogawa DL 750, DL 1600 series and DL 7440 Oscilloscopes into the variables y (y data) and t (time data). The matrices ind_over and ind_under, illegal contain the indices of overranged data points outside the upper/lower limit of the TDS AD converter and indices of illegal values. advantage：permit several traces, e.g. [x(:,1:4),x(:,5)]=wvfreadb_moreinput(filename, 1, [1,2,3,4], 1) )

一段急需的程序，关于ＭＡＴＬＡＢ数字水印方面的，希望对大家有所帮助．(section of the much-needed process of MATLAB digital watermarking regard, we hope to help.)

fisher变换可以将 维空间的样本投影到一条直线上，形成一维空间，这个就是用matlab解决fisher的例题(the fisher transform a sample-dimensional space can be projected onto a straight line, forming a one-dimensional space, this is solved with matlab fisher Example)

ARMA模型预测matlab测试程序，本人亲测好用(ARMA model prediction)

此程序用于实现结构的有限元计算：将patran中的模型的bdf文件中的单元信息和节点信息保存成txt文档，在matlab中调用，就可实现刚度矩阵、质量矩阵的组装，进而有限元计算(This procedure is used to achieve the structure of the finite element method: bdf file of the model in patran unit information and node information is saved into a txt file called in matlab, you can achieve the stiffness matrix, mass matrix assembly, and then the finite elementcalculate)

此为时间序列预测模型的详细说明，并附有详细的程序，可直接下载下来用！(This time series forecasting model for the detailed instructions, along with detailed procedures can be directly downloaded to use!)
