doa估计的各种算法

STL文件读取程序（Matlab）：可以将ASCII格式的STL文件中的数据点信息及网格拓扑信息读出，并显示在屏幕上(a MATLAB program which gets the name of an ASCII STL (Stereolithography) file from the user, reads the 3D graphics information stored in the file, and displays the structure on the screen. )

vmp is the file generate from Brainvoyager which can link vtc file and the 3D image. This toolbox help you to edit vmp file in matlab.

采用带宽为3，中心频率为3的复morlet小波对示例信号进行了分析，并绘出时频图。(Using bandwidth of 3, center frequency is 3 complex morlet wavelet to sample signal is analyzed, and draw the time-frequency diagrams.)

针对常规PID控制不具有自适应能力，对于时变、非线性系统控制效果不佳。提出了将模糊技术与PID控制相结合的控制方式，设计模糊控制器。(Conventional PID control with adaptive capabilities, time-varying, nonlinear system control ineffective. Fuzzy and PID control combined control mode fuzzy controller design.)

里面含有相应的插值函数与相应的拟合函数，都用matlab程序实现了，而且都没有错误。(Which contains the corresponding interpolation function and the corresponding fitting function using the Matlab program, but there are no errors.)

TSP solved by genetic algorithms

针对信号自适应chirplet分解未知参数多、实现起来比较困难的特点，文献[1]提出了一种新的chirplet分解快速算法。该算法利用计算信号的二次相位函数，得到其能量分布集中于信号的调频率曲线上的结论，此时通过谱峰检测可同时获得chirplet调频率、时间中心和幅度的估计；然后通过解线性调频技术获得其初始频率和宽度的估计，仿真结果验证了本文算法的有效性。(this code includs one method for chirplet analasis,that is used in voice and ultra-wave analasys,etc.)
