语音信号线性特征的能量熵特征的计算，这是第一能量熵的源码，希望大家可以借鉴一下(Linear characteristics of speech signal characteristics of the energy calculation of entropy, this is the first energy entropy of the source, I hope we can learn about)

1. BPSK modulation of data which ever you input (default data is “MANIPAL REDDY”). 2. MANIPAL REDDY is changed into ASCII Format and into two-bit format for BPSK Modulation. 3. Chaos is used for spreading the binary bit sequence. 4. Uniformly distributed Noise is added to Spread signal. 5. After reception Chaotic Chip sequence is used to recover message . 6. Filter is used for removing spikes and noise. 7. Note the filter is used is just for showing a little realisitic picture. 8. Appropriate filter should be used. 9. The original data in binary and recovered data in binary format are compared

这是一个用在Matlab中对二维图像进行特征点提取的代码(This function returns IMAGE s SIFT keypoints)

matlab计算地震动反应谱的EPA值，EPA的计算主要是根据美国ATC规范的规定，先计算反应谱，再求取0.1-0.5s的谱均值。(matlab to calculate EPA)

说明：  该程序可以对遥感图像进行分类，使用的方法是BP神经网络。(The program can be used to classify remote sensing images, using the BP neural network.)

说明：  自己编的制作红色小球沿一条带封闭路径的下旋螺线运动的实时动画。(their series produced a small red ball with a closed along the path under the rotating spiral movements of real-time animation.)

一个自己用到的用matlab编写的fdtd源程序，感觉还可以。里面的参数没有设置，可以自己根据需要设置。(Used with its own written fdtd matlab source, feeling okay. Inside the parameter is not set up my own according to their needs.)

实现curvelet变换的软件包,包括curvelet变换,逆变换等功能(performing curvelet transform and inverse transform)
