Assign-3

说明：  用Matlab编写的一款计算调和常数的程序包，附有数据，非常适合想要用matlab计算调和常数的爱好者(Using Matlab prepared a calculation of harmonic constants package, accompanied by data, very suitable for the calculation you want to use matlab to reconcile the constant lovers)

基于非线性扩展卡尔曼滤波的Matlab程序(The extended Kalman filter can not only estimate states of nonlinear dynamic systems from noisy measurements but also can be used to estimate parameters of a nonlinear system. A direct application of parameter estimation is to train artificial neural networks. This function and an embeded example shows a way how this can be done.)

mvdr算法是最小方差无畸变响应波束形成器，它的原理来自是使非期望波达方向的任何干扰贡献的功率最小，但又能保持观测方向的信号功率不变。(mvdr algorithm is the minimum variance beamformer response distortion, its principle is that any interference from the direction of arrival of the undesired contributions to a minimum power, but the power of the signal while maintaining constant observation direction.)

Matlab program for doing image segmentation

双边带调制及频谱仪的设置，如何在高频、低频中观测频谱特性(Modulation and spectrum analyzer with a bilateral setting, how high-frequency, low-frequency spectrum observed)

POWELL算法求最小值，可求取多个函数的最小值，速度和精度都很高。(POWELL algorithms seek the minimum, the minimum can be to strike a number of functions, speed and accuracy are high.)

KNN classifiers, training is training set, testing is test set, D is the distance, D=1 is mandistance D=2 is 欧氏距离 D=3是 infinite norm K is the number of selected neighbors

说明：  柔性连接倒立摆状态方程及开环阶跃响应

可以实现通过matlab GUI界面做串口通信助手的软件(Can be implemented by matlab GUI interface to do serial communication software assistant)
