说明：  用matlab仿真产生双音多频DTMF信号.(Simulation using matlab generate DTMF DTMF signal.)

水声kraken模型程序的使用说明性文章，详细讲解了kraken模型原理以及程序包的使用，非常经典，本站基本找不到类似的！(Acoustic kraken model program using descriptive article gave a detailed kraken model principle and the use of the package, very classic, basic can not find a similar site!)

实现大点数的IFFT变换，先进行小点数IFFT变化，然后再进行过采样滤波，有频谱图及例子(Achieve great points IFFT transform, first have a small point IFFT change, and then over-sampling filter, a spectrum and examples)

这是一个2fsk的跳频系统程序，很有帮助的，(This is a 2fsk hopping system procedures, helpful,)

主要描述Matlab优化实例。主要包括线性规划问题、foptions函数、非线性规划问题、“半无限”有约束的多元函数最优解、极小化极大（Minmax）问题、多目标规划问题、最小二乘最优问题和非线性方程(组)求解。 (The main description Matlab optimization instance. Mainly include linear programming problem, function foptions, nonlinear programming problem, " a semi-infinite constrained multi-function optimal solution, minimization great (MinMax), a multi-objective programming problems, least squares optimization problem and non- linear equation (group) to solve.)

包括主成分分析、因子分析、贝叶斯分析，数据模型归一化，模态振动，对信号进行频谱分析及滤波，调试通过可以使用，matlab程序运行时导入数据文件作为输入参数，IMC-PID是利用内模控制原理来对PID参数进行计算。(Including principal component analysis, factor analysis, Bayesian analysis, Normalized data model, modal vibration, The signal spectral analysis and filtering, Debugging can be used, Import data files as input parameters matlab program is running, The IMC- PID is using the internal model control principle for PID parameters is calculated.)

SVM分类器，包括训练和测试，实用的matlab包。(SVM classifiers, including training and testing, practical matlab package.)

matlab 文件，用于学习m文件，解释m文件的编写及用法(matlab documentation, for learning m paper explaining the preparation of the document m and usage)

是用分形盒维数算图像的分维数，是我研究生的一个作业的程序()
