matlab中一些常用命令汇总，为大家节省时间，多多交流(order)

书本上的几个例子，很好用，可以直接运行。对于初学者比较有用！(Book a few examples of good use, can be directly run. More useful for beginners!)

用matlab语言实现32阶FIR滤波器，并实现气频域和时域仿真(Matlab language with 32-order FIR filter, and to achieve air frequency domain and time domain simulation)

emd经验模态分解 对振动信号进行emd分解后可以得到若干个imf,然后便可以进行希尔伯特黄变换，判断故障。(emd, it is used to analyse a signal)

在Matlab simulink仿真环境中，用恒压法实现MPPT模型仿真。(IN Matlab simulink simulation environment, MPPT model simulation using the constant voltage method.)

matlab中产生高斯白噪声的源程序,通过程序可以产生所需要的高斯白噪声.(Gaussian white noise generated matlab source, it can produce the desired Gaussian white noise through a program.)

说明：  SAR(合成孔径雷达)距离多普勒成像算法分析与仿真(Analysis and Simulation of SAR Range Doppler Imaging Algorithm)

Fixed-Point iteration(Function fixed_point(p0, N) approximates the solution of an equation f(x) = 0, rewritten in the form x = g(x), which is a sub-function the user has to enter. the call to the function fixed_point(p0, N) returns the root of the equation f(x),i.e. the fixed-point of g(x), if the procedure is successful or a sequence of iterates in case something goes wrong. p0 is the initial approximation and N the maximum number of iterations. If, after N iterations, condition |x(k)- x(k-1)| < tol is not satisfied, all iterated values will be displayed, accompanied by a message asking the user to either change p0 in case of divergence or enter another g(x) that does not lead to complex numbers arithmetics. Reasons for the program to go wrong are the divergence of iterates and/or appearance of complex numbers for example with functions involving sqrt(x) when one of the iterates is negative. )

说明：  本源代码可以对提取的光强度信息转换为频域信息，可以做分析之用(Origin of the code can be extracted light intensity information is converted to frequency domain information and analysis can be done with)

用卡尔曼滤波来检测视频中的小运动目标，例子为检测一个运动场景中的乒乓球(Using kalman filter to detect small moving targets in video, example for detecting a movement in the scene of table tennis)
