遗传算法解决求解带约束的优化问题明确遗传算法求解问题的一般思路和编码设计(Genetic Algorithm for solving constrained optimization problems with a clear genetic algorithm from the general ideas and Coding Design)

用MATLAB实现SOM算法改进，非常实用的程序！可以直接使用的！(SOM algorithm using MATLAB to achieve improvements, a very useful program! Can use!)

matlab程序，气象学上画风场，可以添加标尺(matlab procedures, meteorology style games, you can add the ruler)

古典密码学中的一些实现加密的算法，用Matlab实现的。(Classical Cryptography to achieve some of the encryption algorithm, using Matlab to achieve.)

an algorithm to calculate fast fourier transform of sound signal

比较详细的介绍PAPR问题的资料，以及这些问题的解决方法。(failed to translate)

说明：  文档中的matlab源代码主要是针对单回路液位控制系统的PID控制实现，内有simulink原理图(Matlab source code in the document is mainly for single-loop PID control of water level control system to achieve, within the simulink diagram)

说明：   已知某控制系统结构图如下所示,要求设计校正环节G(s),使系统对于阶跃输入的稳态误差为零。使系统校正后的相角裕量γ≥45°，幅值裕量kg≥10db。(Known structure of a control system as shown below, links to design correction G (s), allowing the system to step input for the steady-state error to zero. The system after correction phase margin γ ≥ 45 °, the amplitude margin kg ≥ 10db.)

说明：  数值分析一题， 曲面拟合 5个表达式(that a numerical analysis, surface fitting 5 expression.)
