07 种群竞争模型

这是瑞士卷数据集，isomap的原始数据集，mat格式，好用(Swiss roll data set in mat , originally used in ISOMAP)

说明：  SPWM电压型逆变电路multisim仿真，电力电子技术，(Multisim Simulation of SPWM voltage source inverter, power electronics technology,)

说明：  外点罚函数法的matlab程序，含有图像(The matlab program with an external penalty function method, containing an image)

对于图像进行相关滤波，然后实现对其中目标的跟踪(For the image correlation filtering, and then achieve the target tracking)

一个简单的职工管理系统，管理职工的信息情况(A simple employee management system to manage information on the situation of workers)

用multim2001编写,可以作为电路初学者的学习参考-with multim2001 preparation, as a circuit beginners can learn reference

说明：  LDPC码是一种分组码,其校验矩阵只含有很少量非零元素。正是校验矩阵的这种稀疏性,保证了译码复杂度和最小码距都只随码长呈现线性增加(LDPC code is a block code, and its check matrix contains only a few non-zero elements. It is the sparsity of parity check matrix that ensures that decoding complexity and minimum code distance increase linearly with code length)

说明：  拉格朗日乘子法最优值求解，求解函数的最小值，极小值求解，求解速度快。效率高(The Lagrange multiplier method can solve the optimal value, the minimum value and the minimum value of the function, and the solution speed is fast. Efficient)

通过对MIDI信号的解码及实时音符显示实现，让用户清楚的了解过程(By decoding the MIDI signal and displaying the real-time note, the user can get a clear understanding of the process)

提出了一个新的超声缺陷自动识别系统。该系统采用小波包分解提取超声信号的特征,采用混沌遗传算法来消除冗余和不相关的特征,并采用支持向量机(SVM) 来对缺陷进行识别。-Proposed a new ultrasonic flaw Automatic Identification System. The system uses wavelet packet decomposition extract the characteristics of ultrasonic signals using chaos genetic algorithm to eliminate redundant and irrelevant features, and using support vector machine (SVM) to identify defects.
