运用FFT技术来综合和分析电话拨号的过程，matlab来分解了这一过程，希望能提供帮助( TOUCHTONE Use FFT to synthesize and analyze telephone dialing The dual tone multi-frequency (DTMF) standard specifies that the tone generated by a button on a telephone key pad is the sum of two sinusoids, with frequencies determined by the button s row and column. The dial pad on the upper left allows you to select buttons and generate the corresponding tones. The signal plotted on the upper right is a recording of the FAX number for the MathWorks being dialed. You can replay the entire signal, or select individual segments. The power plot is the magnitude of the FFT of the signal being played. What is the MathWorks FAX number?)

收集的一些CCP协议汽车标定相关的资料，希望能对从事这方面开发的朋友有些须帮助(Collection of some of the CCP protocol auto calibration of the relevant information, hoping to develop in this field to help some friends)

本书收录了众多的matlab的数学建模的算法，例如线性规划、整数规划、非线性规划、动态规划和图与网络模型及方法等有关的众多matlab数学模型。(This book contains a large number of matlab mathematical modeling algorithms, such as linear programming, integer programming, nonlinear programming, dynamic programming and graph and network models and methods for many matlab mathematical model.)

说明：  无源雷达接收机的系统仿真设计，包含频率带宽等信号仿真(System Simulation Design of passive radar receiver, including signal simulation frequency bandwidth)

iris data file for using in matlab

说明：  用于故障诊断研究的vss程序代码，感兴趣的可以看看(The VSS program code for fault diagnosis research can be viewed as interesting)

说明：  基于Simulink（可再生能源）的电力系统仿真 这个程序是用来模拟现代电力系统与可再生能源，如风能，太阳能和电池源集成。(Power System Simulation Using Simulink (Renewable Energy) This program is used for simulating modern power systems integrated with renewable energy sources such as wind, solar, and battery sources.)

说明：  积分分离PID算法的思想是：当被控量与设计的偏差量偏差较大时，取消积分量，以免积分量使系统稳定性降低，超调量增大；当被控值接近定值时，引入积分控制，以消除静差，提高系统精度。(integral separation PID algorithm thinking is this : When the volume charged with the design of larger deviations deviation, the abolition of Integral volume, the volume so integral to reduce the system stability, over-regulation increased; When charged with setting value approach, the introduction of integral control to eliminate static error and improve system accuracy.)

说明：  这是一段利用matlab仿真抛骰子问题的蒙特卡洛算法，要求两个骰子的点数之和大于6并且第一个点数大于第二个点数(This is a simulation using matlab problem throwing dice Monte Carlo algorithm, to ask the two points of the dice and more than 6 points higher than the first and second points)
