3麦克风tdoa定位matlab仿真代码(3, positioning the microphone tdoa matlab simulation code)

This a two dimensional level set code where the interface grows with normal speed equal to one. The code generates a movie showing the interface motion. This code uses a first order Godunov method.

EM algorithm for Gaussian mixture (EM_GM) learning is well known

time difference of arrival

zcr : ampzcr.m -- short time energy and zero crossing rate program vad.m -- endpoint detection

Genetic Algorithm + Neural Network for caracteristic optimization(Genetic Algorithm+ Neural Network for caracteristic optimization)

说明：  程序可求解任意边界条件任意力（需手算或增加m文件将力等效到单元节点）的矩形板的单元受力及应力。(Program can solve any power of arbitrary boundary conditions (to be hand or the equivalent increase in m file will force the node to the unit) unit of the rectangular plate the force and stress.)

matlab 中实现一个四叉树的结构,使用递归过程，整合成一次二向遍历(secure yourself with a simple quadtree in matlab)

this code detect skin of human body and every thing that is same as it

频谱估计 讲的比较详细 里面的ppt文件还有解释 值得一看(spectrum estimation)
