this document present how we use butterworth ,chybi1,chiby2 and recursif fiter using matlab

轨道六根数的MATLAB程序,轨道六根数的MATLAB程序(6 tracks the number of MATLAB procedures, track the number of six MATLAB program)

说明：  这是一个基于MATLAB的三相SPWM逆变电路(This is a MATLAB-based three-phase SPWM inverter circuit)

脉冲压缩，用于雷达信号处理，chirsp信号的时域和频域压缩算法。(range compress，used for radar signal process。)

一种流形学习算法（很好用），解耦，恢复原信号，小波包分析提取振动信号中的特征频率。( A fluid manifold learning algorithm (good use), Decoupling, restore the original signal, Wavelet packet analysis to extract vibration signal characteristic frequency.)

一维电阻率模拟Matlab源代码，很好的Matlab滤波源代码资料(a Matlab program to model 1D complex resistivity effects in electrical and electromagnetic surveys)

包括：使用控制变量蒙特卡洛法和一般蒙特卡洛法的欧洲期权看涨价格程序；使用蒙特卡洛计算定积分；使用B-S公式计算期权价格。 ( Including: European call options price procedure using control variable Monte Carlo method and general Monte Carlo method using Monte Carlo calculation of definite integral use the B-S formula to calculate the price of option.)

汉明码编码和译码，实现自动捡错纠错功能，（7，4）汉明码(Hamming code encoding and decoding, the realization of automatic pick up error correction function, (7, 4) hamming code)

将要分析的数据放在C盘的ELI.xls表的Bay表单中，根据数据多少调整读取范围（修改 b2:f16 此句) 结果有两种，一种是按数据计算权值求出的结果，另一种是参考建议值求出的结果。结果写入C盘的ELI表格，范围要手动根据数据多少调整(The data will be analyzed on the C disk ELI.xls Table Bay form, how much to adjust the data read range (change ' b2: f16' sentence) result, there are two, one is calculated according to weight data the results obtained, the other is the result of reference to find the recommended value. Results written to C drive of the ELI forms, the scope of how much to manually adjust the data)

改程序包里包含中值、均值滤波、自适应中值滤波和一种改进的椒盐噪声滤波程序，前三种是给第四种作对比的，第四种方法对椒盐滤除效果很好。(Change the program package contains the value, mean filtering, adaptive median filter and an improved impulse noise filtering program is the first three compare to the fourth, the fourth method works well for removing salt and pepper.)
