A MATLAB tool for analysis of Transient Otoacoustic Emission signals

为matlba GUI中axes控件添加了放大，平移等功能(offer the funcion of scale, move and so on to the axes in GUI of matlab)

给出卫星适当的初始位置和速度，利用其运动微分方程，求出2－3个周期内的轨道，并画出机械能和动量矩的大小随时间变化的曲线。(Given appropriate initial satellite position and velocity, using the equations of motion, find the 2-3 cycle track, and draw mechanical energy and angular momentum of the size of the curve over time.)

C++ code for computation of the inverse matrix with dimension 3x3.

matlab函数列表以及功能说明，非常实用(matlab function lists, and feature descriptions, very useful)

This package is used for exponential smoothing models

资料中包含利用校验子（错误图样）译码的原理、编码流程图以及matlab的编码，程序中配有注释，通俗易懂。(Information contained in the use of sub-parity (error pattern) decoding principle, flow charts and coding matlab code, the program with notes, easy to understand.)

双极性二进制基带传输系统的仿真和误码性能验证 ①．发送信号的星座图，发送和接收信号的波形，不同信噪比情况下，接收信号的星座图 ②．画出无信道编码时，误比特率的理论曲线和仿真曲线，以及有信道编码时误比特率的仿真曲线 ③．解释以上获得的各种结果的合理性 ④．选做：选用不同纠错能力的信道编码方法，比较信道译码后的误码率(Simulation and Error Performance Verification of Bipolar Binary Baseband Transmission System (1) Constellation diagram of transmitted signal, waveform of transmitted and received signal, constellation diagram of received signal under different signal-to-noise ratio (2) Draw the theoretical and simulation curves of BER without channel coding and the simulation curves of BER with channel coding. (3) Explain the rationality of the results obtained above. (4) Choose: Choose channel coding methods with different error-correcting abilities to compare the bit error rate after channel decoding.)

说明：  基于干涉极值法提取相位功能函数，可以快速提取干涉条纹的相位(The phase function is extracted based on the interference extremum method, which can quickly extract the phase of interference fringes)
