短时傅里叶变换MATLAB代码，主要是用于非线性信号分析(Short-time Fourier transform MATLAB code, mainly for nonlinear signal analysis)

可以求取一维信号的模糊熵,比如心电信号就可以用这个程序来做模糊熵；另外一个是得出混淆矩阵(The fuzzy entropy of one dimensional signal can be obtained.For example, ECG signal can be used to do fuzzy entropy with this program.The other is to get the obfuscation matrix)

说明：  基于matlab上的指纹识别配合ccs接口同时以对应的硬件为平台使ccs和matlab互联达到ccs2.21负责硬件数据获取matlab作为硬件处理的过程(Based on the fingerprint matlab ccs interfaces both with the corresponding hardware platform to interconnect to ccs2.21 ccs, and matlab for data acquisition hardware, as hardware processing matlab process)

萤火虫算法，一种新颖的群优化算法，目前比较流行的有两种，一种是FA，一种是GSO，本代码试GSO的实现(glowworm swarm optimization)

此程序是对齿轮信号进行模拟分析，并通过小波变换进行信号重构(This procedure is to simulate the gear signal analysis and signal reconstruction by wavelet transform)

10个基本阵列，方向60 ，80，85,120,130 通用INR=5dB，用music，capon，线性预测，波束形成等四种算法画出功率谱图。(10 basic arrays, direction 60, 80,85,120,130 common INR = 5dB, with music, capon, linear prediction, beamforming and other four algorithms to draw power spectrum.)

扩展卡尔曼在定位中的一个例子,在滤波分析中很实用(Extended Kalman positioning an example, very useful in filtering analysis)

正在学习MATLAB和仿真的人可以看下，适合新手，内容很详细(Simulation and MATLAB , very detailed content)
