Matlab Script that simulates PID design

说明：  共轭梯度法编程.共轭梯度法是共轭方向法的一种依赖于迭代点的负剃度而构造出来的(Conjugate gradient method programming. Conjugate gradient method is a conjugate direction method relies on an iterative point out negative tonsure and the structure of the)

说明：  差分脉冲编码：通信工程中经常用到的一个实用算法。这里是matlab的实现。(Differential pulse code: Communications Engineering frequently used for a practical algorithm. Here is the realization of matlab.)

给出了三个m文件，分别适用于不同的Shortestpath问题，本程序是工程CT的一部分，属于正演算法，可获得射线路径。每一条均有注释，适合初学者。完美运行。(For the Shortpath, given 3 m files. They are the part of CT for induction. Fit for green hands.)

蚁群算法：matlab编程实现蚁群算法源代码(Ant Colony Algorithm: Matlab programming ant colony algorithm source code)

说明：  自己做的几个涉及到测量的子程序，有坐标反算、排序、角度转换、时间处理、四舍六入、三维显示等等(Yourself a few involves measurement subroutine, are calculated by coordinates, sorting, Angle conversion, time processing, and six into four, three dimensional display and so on)

floyd算法，运用与优化的问题处理，具有高效性和精确性(Problem floyd algorithm, the use and optimization, with high efficiency and accuracy)

面阵阵列天线二维方向图仿真，代码简单易懂(The two-dimensional surface bursts columns antenna pattern simulation, the code is easy to understand)

类似于小波变换，使用奇异值分解理论检测信号的奇异点。(Similar to the wavelet transform, using the singular value decomposition theory of singularity detection signal.)
