Two functions, num2bin and bin2num are provided. num2bin takes a double and converts it to a binary string representation. bin2num is its inverse operation. It can be used in a numerical analysis course when floating point arithmetic is discussed. (Two functions, num2bin and bin2num are provided.

主要模拟的是信号光在增益光纤中放大的过程(Main simulation signal light is amplified in the gain fiber in the process)

QAM解映射程序，在接受端，对发送端经过调制的信号解调，恢复出原始的信息。(QAM demapping process at the receiving end, the transmission side demodulates the modulated signal to recover the original information.)

包括卡尔曼滤波主文件和函数文件,希望大家一起学习。(Including the Kalman filter master file and function file)

根据多行三列的实验数据（x,y,signal)作出contourf图。其中x,y为二位空间位置（或其他概念的二维），signal为在该位置的信号。此代码先将数据按位置不同求平均，再将signal按照其对应的x,y分配到二位矩阵内。最后作图。编这个代码的初衷是为了制作大脑hippocampus区域place cell 活动性的contour 图。(it s a code i made for plotting a contour graph of experimental data (x,y,signal). The data should be n*3 arrays which cannot be plot into contour directly. In fact, it can subplot 6*6 graphs or more, but speed might be slow..... especially, when you want more detailed graphs.)
