经典AR模型系数求解，burg法.根据原理手编，希望对大家有帮助。(the method of burg to get the coefficients of AR model)

Matlab不用说就知道是什么了, 在图像处理中Matlab也很强大, 奉上一个教程.(Matlab do not know what it says in the Matlab image processing is also very strong, just give a tutorial.)

大学教材中数值计算引论中的matlab程序(University textbook Introduction to the numerical calculation matlab program)

matlab源程序代码，基于BP网络算法用于股票的预测，有修正的过程，过程中有些代码缺少！(matlab source code, based on BP neural network algorithm is used to predict the stock, during some of the code is missing! ! !)

《MATLAB实用教程---控制系统仿真及应用》的配套光盘，不但便于读者使用，而且给任课老师提供了生成数量不限的 练习题的功能，便于因人施教。(" MATLAB tutorial--- practical control system simulation and application of" matching discs, readers not only easy to use, but also to the classroom teacher provides a unlimited number of exercises build functional, easy to teach from person to person.)

说明：  压缩包里包含了无约束优化问题常用的几种求解方法的源程序：变量轮换法（variable_rotation.m）、最速下降法（steepest_descent.m）、修正牛顿法（modified_newton.m）、共轭梯度法（conjugate_gradient.m）。另外，coefficient_matrix.m为目标函数系数获得矩阵，minval.m为最小值计算函数，gradient.m为梯度计算函数(Compression bag contains unconstrained optimization problems of several commonly used method of source: variable rotation Act (variable_rotation.m), steepest descent method (steepest_descent.m), as amended Newton (modified_newton.m), conjugate gradient method (conjugate_gradient.m). In addition, coefficient_matrix.m as the objective function coefficients obtained matrix, minval.m function for the minimum calculation, gradient.m for gradient calculation function)

This is a short code script to describe CDMA coding and decoding mechanisms

这是一个关于二维的FDTD的源代码，主要模仿电磁波传播的传播，对于做天线，雷达的朋友有帮助(This is one of the two dimensional FDTD source code, mainly to imitate the propagation of electromagnetic wave propagation, for antenna, radar has to help a friend)
