这是在研究神经网络的过程中，自己编写的用于模式识别的MATLAB源代码，相信对于神经网络的学习者有帮助，其中也给了测试数据！ (This is the study of neural networks in the process of their preparation for the MATLAB source code for pattern recognition, neural networks and I believe that learners be helpful, which also gave the test data!)

题目：有1、2、3、4个数字，能组成多少个互不相同且无重复数字的三位数？都是多少？(Title: There are 1,2,3,4 digits, how many can be formed from each other and without duplication of the three-digit numbers? How many are?)

對於影像處理的分析教學,以及解述數位訊號處理的應用(Analysis of teaching, as well as image processing paraphrase digital signal processing applications)

基于灰度的归一化匹配算法：将原图以及匹配图灰度化，算出相关系数后得到匹配区域。(Based on Gray' s normalized matching algorithms: the original image and the gray level of matching graph, calculate the correlation coefficient obtained after the matching area.)

空气质量降维B-P神经网络评价法及其MATLAB实现 简介: 用主成分分析将多维空间的样本数据降维到低维空间，将其作为BP网络的输入。BP网络的算法采用LM优化法。描述了该网络的MATLAB程序语言实现过程。(Air quality dimension reduction BP neural network uation method on MATLAB Introduction: Using principal component analysis will drop the sample data in multidimensional space dimension to low-dimensional space, as the input of BP network. BP network algorithm using LM optimization method. The network describes the MATLAB programming language implementation process.)

自己建的PMSM矢量控制仿真模型，该模型完全基于simulink基础库创建，没有用到powersystem模型库。(Vector control of PMSM to build their own simulation model, the model based entirely on the simulink based library to create, not used powersystem model library.)

说明：  现代数字信号处理中基于互相关函数的music方法(Modern digital signal processing in the cross-correlation function-based method of music)

说明：  闭环控制系统输入信号为阶跃信号，受控对象的传递函数为3 2 1 ( ) 2 5 s G s S s s      。(Closed loop control system for the step input signal, the transfer function of the controlled object 3 2 1 () 2 5 s G s S ss      .)

found on the Windows operating system — by far the most common operating system in use today
