有多普勒频移的海底混响单元散射模型（matlab）(the seafloor reverberation unit scattering model with Doppler frequency shift)

this code in used in neural network mlp with back propagation training algorithm and geradian descends algorithm for optimization.in some of this codes I used full propagation algorithm or mlp one layer or two layer with different activation function.this code can be use for prediction or control system by useing neural networks.

chirp信号生成，以及匹配滤波实现，卷积实现(chirp signal generation and matched filtering to achieve)

计算空间几何距离的MATLAB计算机算法(Spatial geometric distance calculation algorithm MATLAB computer)

this code perform boxcounting algorithm on picture

基于RSSI的距离测量 matlab 将接收信号强度RSSI转化为距离，发射信号经衰减到达接收端,根据接收信号的强弱计算T-R距离(RSSI-based distance measuring the received signal strength RSSI matlab converted into distance, attenuated transmitted signal arrive at the receiver end, according to the strength of the received signal the calculation TR)

watermaking algorithm to crypting image to images

MATLAB设计简易计算器 运行通过,方便灵活(MATLAB simple calculator designed to run through, convenient and flexible)

This function obtains a unitary matrix Q such that: d=diag(Q *diag(lmd)*Q). In other words, it gives a way to generate a matrix with given eigenvalues and diagonal elements.
