距离计算——matlab :利用MATLAB语言编写的用于计算两点间距离的M文件(Distance calculation- matlab)

用matlab实现的聚类，效果很好，里面有部分数据，点击可以直接运行(Cluster with matlab to achieve good results, which are part of the data, click directly run)

matlab从入门到精通全书源代码，希望对大家有用(matlab book from entry to the master source code, useful for all of us hope)

说明：  对sinc函数进行内插后的误差比较（matlab）(Of the sinc function interpolation error after the comparison (matlab))

This is qpsk ber curve simulation.

课程设计用到的qpsk，包括qpsk信号的调制与解调，可运行，有图(Curriculum design qpsk used modulation and demodulation, can be run, there are plans。)

说明：  寻找三次样条多项式需要求解大量的线性方程。实际上，给定N个断点，就要寻找N-1个三次多项式，每个多项式有4个未知系数。这样，所求解的方程组包含有4*(N-1)个未知数。把每个三次多项式列成特殊形式，并且运用各种约束，通过求解N个具有N个未知系数的方程组，就能确定三次多项式。 (find cubic spline solving polynomial need a lot of linear equations. In fact, given N breakpoints, it is necessary to look for N-1 cubic polynomial, each with four polynomial coefficients unknown. Thus, by solving the equations contain 4* (N-1) unknown. Each cubic polynomial Timing special form, and use of various constraints, by solving N with N unknown coefficient equations, we can identify three polynomial.)

里边有几个关于卡尔曼滤波的程序，非常易用简单，大家可以拿来学习学习，特别是要自适应滤波的(Inside there are several application of kalman filtering, is very simple and easy to use, people can learn to learn, especially to the adaptive filter )
