自己最近几个月学习C,C++时,疑难问题的笔记，希望对刚刚学习C++的新手有所帮助。(my C++ studying note.)

matlab编写的Gauss_Seidel迭代算法求解方程组的根 (iterative algorithm matlab prepared Gauss_Seidel root of solving equations)

波达方向估计算法仿真中的基于解相干的MUSIC源程序 中的矩阵分解算法(Simulation of DOA estimation of MUSIC-based decoherence source in the matrix decomposition algorithm)

说明：  老外的电机学教材，最为重要的是有相应的MAtlab代码，每一章都有，十分详细，学习电机的必备工具书，文件是在太大，此处上传chap6的源码(Foreigners motor learning materials, the most important thing is there is a corresponding MAtlab code, each chapter has a very detailed study of the motor necessary books, documents are too large to upload chap6 source code here)

调制与解调用于随机共振的微弱周期信号检测,随机共振经典论文(failed to translate)

a filtering technique in matlab software.

simulates the motion of a pendulum in 3-D usin RK-4.

元学习算法的一种——IDBD算法，实现信道均衡仿真(IDBD, a meta-learning algorithm, realizes channel equalization simulation)

用matlab编程实现彩色图像的局部分割，下载后解压即可(Programming using matlab partial color image segmentation, can be downloaded after the decompression)

说明：  讨论资金积累、国民收入、与人口增长的关系. （1）若国民平均收入x与按人口平均资金积累y成正比，说明仅当总资金积累的相对增长率k大于人口的相对增长率r时，国民平均收入才是增长的. （2）作出k(x)和r(x)的示意图，分析人口激增会引起什么后果. (Discussion of capital accumulation, income, and the relationship between population growth. (1) If the national average income per x and y is proportional to the accumulation of funds that only if the total funds accumulated in relative growth rate k of the relative growth rate than the population r when per capita income is growing. (2) to k (x) and r (x) of the diagram, analysis of population growth will cause the consequences.)
