这个是matlab下的小波分析在信号处理中的应用的全部代码(Matlab is the wavelet analysis of the signal processing of all code)

蛙跳算法（SFLA）是一种全新的启发式群体进化算法，具有高效的计算性能和优良的全局搜索能力。(Leapfrog algorithm (SFLA) is a new heuristic population evolutionary algorithm, with high computational performance and excellent global search ability.)

This is the Pattern Recognition toolbox from research Group of the TU Delft

说明：  this file along with others coded "finger" construct the complete source code for fingerprint recognition system. do enjoy using it,

函数种类全面的matlab数据统计识别工具箱(Matlab data function type of comprehensive statistical identification toolbox)

an inferior assistant or a channel administrator hopes to append some additional message, such as the origin information, image notation or authentication data, within the encrypted image though he does not know the original image content. some parameters are embedded into a small number of encrypted pixels, and the of the other encrypted pixels are compressed to create a space for accommodating the additional data and the original data at the positions occupied by the parameters

说明：  用S变换法对电离层对海杂波的污染进行校正(S transform with the pollution of the ionospheric correction sea clutter)

一些源程序和一些电子课件，还有数字信号处理试验，很不错~！(Some source code and a number of electronic courseware, as well as digital signal processing test, very good ~!)

验证了Matlab中用于计算时延的Align_Signals模块(test the block of Align_Signals)

说明：  bp神经网络算法的matlab源代码，挺有用的。(bp neural network algorithm matlab source code, quite useful.)
