混沌时间序列算法中进行FFT变换程序，求解平均周期及功率谱。(Chaotic time series algorithm the FFT transform procedure for solving the average cycle power spectrum.)

自由空间E和H场的相位差和振幅衰落，可以显示波形。场特性，方向图，增益等(Free-space E and H field phase and amplitude of the decline can display waveforms. Market identity, direction map, gain, etc.)

小波分析 时频工具箱。做小波变换时很有用。大家可以参考。(Time-frequency wavelet analysis toolbox. Useful to do wavelet transform. We can refer to.)

基于matlab的程序讲解，综合了所有知识及仿真，希望能帮助你学习(Combines all the knowledge and simulation matlab-based program to explain, hope to help you learn)

说明：  极坐标牛拉法和PQ分解法计算IEEE14节点(Calculation of IEEE14 nodes by polar coordinate niula method and PQ decomposition method)

二维插值的应用。二维插值主要应用于图像处理和数据的可视话。主要方法有：最邻近插值；双线形插值；三次样条插值等方法。该源码可以看出其中区别。(Application of two-dimensional interpolation. Two-dimensional interpolation is mainly used in image processing and visualization of data words. Main methods are: the nearest interpolation double linear interpolation cubic spline interpolation and other methods. The source can be seen the difference between them.)

说明：  语音信号分析软件，提取美尔倒谱系数等等功能(Speech signal analysis software, extract Simmel cepstral coefficient features, etc.)

说明：  该软件和代码实现的功能是对图象的加密和解密,运行环境是Xp+matlab,代码中有说明,很容易看明白.(the software code and the functions of the image of encryption and decryption, the environment is Xp Matlab, the code is described, it is easy to see to understand.)
