用平行截面法讨论由曲面z=x^2-y^2构成的马鞍面形状.m(code)

自编的FFT、DTFT程序用于频谱分析，Rife是一种频谱校正方法，分别给出了以上算法的Matlab程序并且画出了图形。已调试通过。(FFT、DTFT codes writen by Matlab,for spectrum analyse.Rife is a method for spectrum correction.Figures are also given.These codes has been tested already.)

说明：  该matlab程序是一个小波包消噪程序，去噪效果明显，新手可以学习下(The matlab program is a wavelet packet de-noising procedure, de-noising effect is obvious, the novice can learn under)

简单的OFDM流程，使用matlab自带的QAM函数，适合初学者，包含FFT，循环前缀，串并变换等(OFDM simple process, using the built-in QAM matlab function, suitable for beginners, including FFT, cyclic prefix, string and transform)

数据处理及误差分析采用了matlab软件来实现，它的界面虽然没有VB等直观简便，但其可调用的函数多，实现起来比较方便，程序中已经实现的功能有： （1）求算术平均值； （2）求残余误差（绝对误差）； （3）求标准差； （4）判断粗大误差，如果发现粗大误差,剔除粗大误差后再进行计算； （5）判断数据是否具有线性误差或者周期性误差。 (Data processing and error analysis using matlab software to achieve, its intuitive interface, while not VB so simple, but its function can be called many realize it was easier, the program has been implemented features are: (1) Find the arithmetic mean (2) Find the residual error (absolute error) (3) Find the standard deviation (4) to determine gross error, if found to gross error, calculated after excluding gross error (5) to determine whether data has linear error or Periodic error.)

MATLAB及Simulink使用练习,单回路系统Simulink动态仿真,汽温控制系统Simulink动态仿真,给水控制系统Simulink动态仿真(The use of MATLAB and Simulink exercises, single-loop system dynamic simulation of Simulink, Simulink steam temperature control system dynamic simulation, water supply control system for dynamic simulation of Simulink)

单一频率的正弦相关法动态测试系统的测试方法简单，不需要对系统进行辨识。只需要观察被测系统输出信号的相差和幅值变化。通过扫频的方法测量在不同的频率点下的幅值和相位变化。在工程应用中，只需要知道被测系统的相位变化在正常的范围内就可以视系统的动态性能正常。该仿真算法只是建立了一个模型。在实际运用时还需要变换测试信号的频率和周期。(A single frequency sinusoidal correlation method of testing dynamic testing system is simple, does not require system identification. Only need to observe the difference between the measured system output signal and amplitude change. Swept through the method of measurement points at different frequencies under the amplitude and phase changes. In engineering applications, only need to know the system under test changes in the normal phase it may be possible within the framework of the dynamic performance of the system to normal. The simulation algorithm is the establishment of a model. In the practical application of test signals also needed to change the frequency and periodicity.)

mathmatics学习资料,比较实用,亲身感受(mathmatics learning materials, more practical, personal experience)

一个简单的IIR滤波器实现编程，已经过调试，完全正确可用(A simple IIR filter programming, has been debugging, can be used entirely correct)

说明：  这是基于帧差法对运动目标检测的代码 希望对大家有用(This is based on frame difference of the moving target detection code)
