DMI_S

交错网格有限差分正演程序，matlab语言，适合于刚入门做地震波正演的新手(seismic wave modeling)

自动叠加，很好用的，哈哈，费了老大的劲搞的啊！！！！！(Automatic stacking )

HARDLIM - 阈值传递函数 表示close的最上面的矩阵； 用变量s来表示open的最上面的矩阵(HARDLIM- threshold transfer function that close the top of the matrix express variable s to open the top of the matrix)

说明：  lena图像的分解将规范化后的图像的数据格式由适合显示图像的uint8格式转换为适合数值处理的double格式，再调用二维小波分解函数进行图像分解，最后为了清晰地显示分解图像的塔式结构，在图像的相应区域绘制若干分界线。 (lena image after decomposition of the standardized image data format suitable for display by the image is converted to uint8 format suitable for numerical treatment of the double format, and then call the function of two-dimensional wavelet decomposition for image decomposition, and finally in order to clearly show the decomposition of the image of the tower structure , the corresponding region in the image number of the line drawn.)

哈希函数的matlab代码，此函数不可逆，具有加密功能。(Hash function matlab code, this function is not reversible, with encryption features.)

matlab传染病sis及相关模型的图的模型，及运用(Matlab infectious disease sis and related model diagram model, and application)

该程序，完成Matlab对音频信号的低通处理仿真。有前后频谱图对比！(The program, the completion of the Matlab simulation low pass processing on the audio signal. Before and after the spectrum in Fig contrast!)

在：1）理想无噪生条件，2）SNR=10dB，3）SNR=20dB，4）两径衰落信 道{0, 0}、{-6dB，-10symbol}条件下，分别产生 1000 个符号的 QPSK、8PSK、 16QAM 星座点， 画出信号序列的星座图， 提交电子版信号产生、 加噪、 显示的*.m 程序和电子版 WORD 报告。 报告要求给出原理描述、 框图和分析说明输出结果。(In: 1) an ideal noiseless Health conditions, 2) SNR = 10dB, 3) SNR = 20dB, 4) two-path fading channel {0, 0}, {-6dB,-10symbol} under conditions generate 1,000 symbols QPSK, 8PSK, 16QAM constellation points, draw constellation signal sequence, submit an electronic version of the signal, noise, display*. m procedures and electronic WORD report. Reporting requirements given Principles, and the analysis shows a block diagram of the output.)

堆栈自编码，通过两个稀疏自编码的堆叠和softmax分类模型，实现手写体的分类。(Stack self-encoding, since encoding by two sparse stack and softmax classification model to classify handwriting.)

说明：  利用复高斯随机矩阵来模拟随机散射介质模型(The complex Gaussian random matrix is used to simulate the random scattering medium model)
