GM(1,1) Predictor (Grey Model)

说明：  本程序一维数据的EM算法实现，稍作修改就可以成为多维数据的EM算法实现。(EM algorithm for one-dimensional data of the program implementation, minor modifications can become the cube of the EM algorithm.)

巴特沃斯滤波器，切比雪夫滤波器，椭圆滤波器设计及比较，同样的设计参数指标，在同一张图中比较三种滤波器的幅频响应波形，并用统计图画出各滤波器所需阶数。(Butterworth filter, Chebyshev filter, elliptic filter design, the same design parameter index, with a figure in the comparison of three filter frequency response waveform, and use statistical picture of the desired order of each filter.)

使用MATLAB完成turbo码的编码,在给定生成多项式交织映射表和删余选择的情况下进行TURBO的编码。主程序为encederm.m,调用子程序rsc_encede.m和encode_bit.m(Turbo code using MATLAB to complete the encoding, in a given generation of polynomial mapping table and delete intertwined choice than under the TURBO code. Main program for encederm.m, call Subroutine rsc_encede.m and encode_bit.m)

变换编码的实现，对初学者还是值得参考的 比较有用的

很好的学习FFT的程序，易于理解，便于学习，具有很好的参考价值(Learning the FFT program, easy to understand, easy to learn, have a good reference value)

激光回馈的计算。回馈水平、泵浦功率、移频频率对弛豫振荡的影响。(Calculation of laser feedback. Back level, the pump power, shifting frequencies influence on the relaxation oscillation.)

把区域划分成矩形网格，找到每个网格的中心点，把每个网格当做一个圆环计算每个圆环的磁场，然后调用linprog函数就求出场分布了。不要求你把线圈矩形化，也不要求屏蔽场。(The region is divided into rectangular grids and the center points of each grid are found. Each grid is used as a circle to calculate the magnetic field of each ring, and then the field distribution is called by the linprog function. It does not require you to rectangle the coil, nor does it require shielding.)
