利用神经网络进行台风分类的matlab程序，主要将台风分成三个阶段。(Using neural network the typhoon classification Matlab program, the main typhoon is divided into three stages.)

实现两个序列的循环卷积，输出卷积后的序列结果(Implement circular convolution of two sequences, the results of the output sequence after convolution)

Finland Matlab cannot do regular meshes for non-regtancular regions. However, one can manually do very coarse regular meshes for these type domains. The difficulty is with the edge data e. If this data does not correspond to the orientations given by the PDEtool geometry files, refinement will not work. The function drawedges() will display the order of the edges and their segment numbers. However, this function does not tell how the edges are oriented. However, just run the visualization, and if the refinement does not work correctly, you know the problem is with the orientatino of the edge. Remember to also correct the last two rows of the matrix e when changing the orientation. (See the documentation for initmesh for more info.)

说明：  对离散数字信号实现QPSK调制，输出调制后的信号(Implementation of discrete digital signals QPSK modulation, the modulated signal output)

光栅尺，随意改变光栅尺的长度，光栅缝宽随着光栅尺长度的变化而变化(Grating, grating arbitrarily change the length of the grating with the grating length slit width varies)

Matlab code for Anti-notch filter implementation

Okumura analyzed path-loss characteristics based on a large amount of experimental data collected around Tokyo, Japan. He selected propagation path conditions and obtained the average path-loss curves under flat urban areas. Then he applied several correction factors for other propagation conditions, such as: Antenna height and carrier frequency Suburban, quasi-open space, open space, or hilly terrain areas Diffraction loss due to mountains Sea or lake areas Road slope Hata derived empirical formulas for the median path loss (L50) to fit Okumura curves.

使用CMakeList重新组织的SBA，即稀疏矩阵光束法平差算法，希望对大家有用(Use CMakeList reorganize the SBA, namely sparse matrix bundle adjustment algorithm, we hope to useful)

matlab PID simple s model pid最简单的S模型，可以自己加入扫频信号，就可以看开环伯德图了(matlab PID simple s model)

papr to differenrt number of subcarrier: we put N = 256,512,1024 and show the output ofp ccdf with papr when we use QPSK modulation. The PAPR ratio is a measure of the dynamic range in OFDM signals. Thus high PAPR induces a high dynamic range which describes high variability in the signal range. complex data sequences are input to the IDFT of an OFDM transmitter then at the output of the IDFT, real and imaginary parts are obtained.
