关于matlab的多分类问题的几篇文章，对于学习matlab 中的svm 多分类问题有帮助(Multi-classification on matlab several articles for learning in matlab svm multi-classification helpful)

PID 控制器，实现PID控制器的计算，采用MATLAB仿真离散系统的控制结果(simulation of PID controller in MATLAB to realize the computation of PID algo in MATLAB for discretized system.)

一种叫做优劣排序结果与顺序结构评估法的决策方法，可用于多目标选择最终解(a decision making method called Preference Ranking Organization Method for Enrichment Evaluation, PROMETHEE, can be used for selecting the final solution of multi-objective optimization)

说明：  Patton Coupla 工具包，包含常见的时变和非时变Copula代码(Patton Coupla Toolbox)

FDTD方法的书，书中有代码，很不错，可以看看(FDTD)

可以通过输入刚度或阻尼数组，生成刚度（阻尼）矩阵。(The stiffness (damping) matrix can be generated by input stiffness or damping arrays.)

一些sar数据，matlab文件，希望对大家有用(Some sar data, matlab file, in the hope that useful)

input: fun x(t) t min & t max a df T = t_max-t_min fs = a*1/T 输入1：方程，xt；输入2，3：信号起始时间；输入4：选取的采样周期是信号长度倒数的倍数， 默认为50；输入5：频域分辨率，默认为0.3 输出频域信号和频域范围 为了提高fft的速度，频域信号长度是2的次方( Input: fun x (t) t min & t max a df T = t_max-t_min fs = a* 1/T Input 1: Equation XT input 2,3: signal start time input 4: select the sampling period is the reciprocal multiples of the signal length, default is 50 input 5: frequency domain resolution, default is 0.3 of the output frequency domain signal and the frequency domain in order to improve the speed of the FFT, the frequency domain signal length is a power of 2)

说明：  MATLAB 有哪些主要功能? 初学者应如何利用这一数学软件去解决自己的 问题？要解决这些问题，应该尽快熟悉一些常用命令，了解它们的功能和使用 格式。(What are the main functions of MATLAB? Beginners how to use the mathematical software to solve their own problems? To solve these problems, should be familiar with some commonly used command as soon as possible, understand their function and use format.)
