this a program that gets data from excel and sets zero to blank cels.

说明：  利用matlab绘制bragg光栅的反射谱，入射光谱范围为1548-1552(Bragg grating matlab rendering reflection of spectrum.The incident spectral range for 1548-1552.)

自适应算术编解码，按paper编写，压缩包中附有paper。(adaptive arithmetic coding and decoding, prepared by the paper, compressed paper attached.)

此程序为测试窗函数宽度对时－频分辨率的影响，即测不准原理，对时间分辨率和频率分辨率只能取一个折中，一个提高了，另一个就必然要降低，反之亦然。(This procedure for the test window function width on- frequency resolution, that is, the uncertainty principle, the time resolution and frequency resolution can only take a compromise, an elevated, and the other is bound to reduce, and vice versa .)

说明：  该程序给出了OFDM信号以及频谱分析，也插入了保护间隔(the procedure given OFDM signal and spectrum analysis, insert a protective partition)

说明：  直流微网继电保护策略实现S-function的M文件，主保护为母线直流差动保护，基于小波分解的高频故障电流保护，后备保护为过电流保护，针对系统为2进2出的微网，只需将电流值输入，其中第一个输入变量为开关，为保护算法控制开始/关闭。(The relay protection strategy of DC microgrid realizes the M file of S-function. The main protection is busbar DC differential protection. The high frequency fault current protection based on wavelet decomposition and the backup protection is overcurrent protection. For the microgrid with 2 in and 2 out of the system, only the current value is input. The first input variable is switch, which starts/closes for the control of the protection algorithm.)
