RLS源程序代码，方便学习和使用改进的最小二乘法，加以修改，随心所欲！(RLS source code, easy to learn and use to improve the least squares method, modify, anywhere!)

说明：  使用hough 变换检测直线，参数可以任意设定，程序说明详细。(Using the hough transform to detect straight lines, the parameter can be set, detailed description of the procedures.)

MIMO（多输入多输出）系统的仿真实现，及性能分析(the simulation of MIMO （multiple-input and multiple-output）system and performance analysis)

说明：  主成分分析法主要算法程序, 里面有详细解释.(Principal component analysis procedure main algorithm, which has a detailed explanation.)

用matlab语言实现Butterworth滤波器的算法，经过调试可以运行！(using Matlab language Butterworth filter algorithm, After debugging can run!)

这是我们参加2011年全国大学生数学建模大赛，做A题的论文和matlab程序，当年获得国奖。 利用此程序可以进行污染源位置反演计算，以及其他类似服从高斯扩散模型的源项反演。 计算量小，简单易懂。(Detect of Pollution source in city.2011 China Undergraduate Mathematical Contest in modeling Q_A.)

matlab中的pn码仿真 PN码的仿真实验 pn码在通信系统中占据了重要的位置，在即将到来的3G通信中比较重要(the pn Matlab simulation code PN code simulation pn code in communications systems occupy an important location in the upcoming three G communications more important)

说明：  direct transform method for data

说明：  求解电荷中性方程的matlaB程序,主要是求解一个数值方程，求解量为费米能级，得到能级后就可以算出电子和空穴的浓度。(Solving the charge neutrality equation matlaB procedures, mainly to solve a numerical equation solving capacity of the Fermi level, by level can be calculated after the electron and hole concentrations.)

该程序主要对非球面镜进行波面拟合，首先读入采集的离散面型数据，可以是从椭圆曲面，抛物面等采样得到，也可以是通过其他软件计算得到的数据。然后将数据用Zernike多项式进行拟合得到非球面表达式各项的系数。(The program on the aspheric wavefront fitting, first read into a collection of discrete surface data can be Sampling from the oval surface, the paraboloid, can also be calculated data obtained by other software. However After aspherical expression obtained by fitting the data with Zernike polynomials coefficient.)
