说明：  对一组转子信号的去噪和计算李雅普指数，相关的程序都包含在内(Calculating a set of de-noising and rotor signal Lyapunov exponent, related programs are included)

产生不同频率、不同幅度的两种正弦波信号 对两个信号进行叠加并做频谱分析 还原原来两个信号（LPF)(Produce different frequency, the two sine wave signals of different magnitudes of the two signals are superimposed and do spectral analysis to restore the original two signals (LPF))

说明：  使用matlab实现ofdm经过PA后在接收端进行失真抵消算法的仿真，其中调制方式包括mqam或mpsk(After the realization of OFDM using matlab at the receiving end after the PA distortion cancellation algorithm to carry out the simulation, which includes modulation MQAM or MPSK)

本组设计的声音导引系统使用双MCU结构，采用基于时间差的声源定位算法（利用三路接收器的时差信号）结合PID算法判断并控制移动声源的速度。本设计的特色在于使用四阶Butterworth带通滤波器对声音信号进行处理，使其具有较强抗干扰能力。且系统设计性价比高，功耗低。(Our group design the Sound Guidance System based on Bi-MCU configuration, using time difference sound source orientation arithmetic（the time difference signal from three receivers）combining PID arithmetic to determine and control the mobile sound source’s velocity. The feature of the designation is processing the sound signal by four-order Butterworth band-pass filter. This enhances the anti-jamming ability. Furthermore, the system has the high performance and low price.)

有限元前处理的一个小程序，包括网格的划分等，比较有用(A finite element pre-processing program, including the division of the grid, the more useful)

三维重建技术的研究是计算机视觉学科的一个重要领域，而双目视觉则是三维重建中的一项重要技术，它利用左右摄像机拍摄出的立体图像对，依据其中包含的几何关系将场景的三维信息重构出来。(Three-dimensional reconstruction of the research is an important subject of computer vision field, while binocular vision is three-dimensional reconstruction of an important technology, which uses about a three-dimensional camera image pair, Yi Ju contains the three-dimensional geometry of the scene Reconstruction of information out.)

提取图像中的红色，并且使红色部分变为白色，其余部分变为黑色。(get the red color area from a picture, and turn the red part into white, and the rest into black)

用极限稀疏矩阵对图像分类，该方法快速简单，代码少，效果好(An ultimate sparse matrix for image classification, the process quick and easy, less code, the effect is good)
