双峰法，迭代法，最大熵阈值分割，初学者，大家共同交流学习！(rs image matlab iamge segmentation)

gabor变换是非平稳信号处理的有效方法之一，在时频平面内可获得最佳划分(gabor transform one of the effective methods of non-stationary signal processing, get the best in the division of the frequency plane)

将输入d进行扩张，方法是在d的每个数据中插入M-1个零值。 如输入d=[1,2,3,4] M=3 输出out=[1 0 0 2 0 0 3 0 0 4 0 0](To expand the input d, the method is to insert each data d, M-1 zero value. If the input d = [1,2,3,4] M = 3 output out = [1 0 0 2 0 0 3 0 0 4 0 0])

南信大系统模拟与仿真的考试程序，其中一个题目，任课老师是袁老师哦(failed to translate)

Implementation of two layer multiperceptron neural networks

AHP层次分析法计算判断矩阵的最大特征值,是学习PCA特征提取的很好的学习资料，STM32制作的MP3的全部资料。( Calculate the maximum eigenvalue judgment matrix of AHP, Is a good learning materials to learn PCA feature extraction, STM32 all the information produced by the MP3.)

对于端面抽运的双包层光纤激光器，利用速率方程对脉冲输出能量进行数值仿真(In the end pumped double clad fiber laser, the output energy is numerically simulated by the rate equation)

说明：  利用BP神经网络设计指纹识别算法，给神经网络提供每一模式类中的一些样本作为训练样本。BP网络经过学习，不仅能够识别已训练过的样本，而且能够识别未出现过的样本。利用神经网络的泛化能力，提高指纹识别算法的识别率，图像增强、提取指纹特征(BP neural network is the first mock exam to design fingerprint recognition algorithm, and it provides samples for each neural network as training samples. After learning, BP network can not only recognize the trained samples, but also recognize the samples that have not appeared. The generalization ability of neural network is used to improve the recognition rate of fingerprint recognition algorithm, image enhancement and fingerprint feature extraction)

无约束问题最优化方法的核心问题是选择搜索方向。 以正定二次函数为例，来观察两个方向关于矩阵Ａ共轭的几何意义(Unconstrained optimization problems are most core issue is to choose the search direction. In definite quadratic function, for example, to observe both directions on the matrix A conjugate geometric meaning)
