说明：  这个程序和我上传的上一个程序有关，它可以将上个程序收集到的频谱数据进行拼接，从而在全频段进行展示，还能计算频谱上的信号频谱带宽和频点 主要参数 start_freq %扫频中心频率fc的起始频率， stop_freq %扫频中心频率fc的截止频率 rtlsdr_fs %每一次扫频的采样频率，改变他会影响每次扫频的带宽 nfrmhold %每次扫频的帧数 nfft %fft点数 overlap %扫频频谱的重叠率(dataspecrumcatch, catch the spectrum and It can also calculate the signal spectrum bandwidth and frequency point on the spectrum)

用块匹配法进行运动估计的matlab实现方法(block matching method used for motion estimation method of Matlab)

this is a very good mfile for small signal analyze

用于大气辐射传输模型modtran5的matlab程序，可读取编辑tape5文件，运行modtran以及读取运行结果。(It provides a set of functions (called “methods” in object-oriented programming terminology) that ease the handling of MODTRAN cases. These include methods to read the tape5 file format into a Mod5 class “instance” or “object”, alter the case instance described in the file, write the tape5 format back to a file, run MODTRAN on the case and read various results from MODTRAN output files back into Matlab.)

基于matlab的基本粒子群优化算法，可应用与最优潮流计算等(Matlab-based optimization of the particle swarm algorithm can be applied with optimal power flow calculation)

ordeig.m——主程序，调用后两者，计算特征值，按顺序排列，使虚部递减 pois.m ——对于平面Poiseuille流通过切比雪夫你拟谱法离散化生成O-S矩阵 Dmat.m ——求解切比雪夫微分矩阵 (ordeig.m main program, after calling two, computing eigenvalues ​ ​ in sequence, so that the imaginary part of diminishing pois.m- for plane Poiseuille flow through Chebyshev spectral method you intend to generate discrete OS matrix Dmat.m- Solving Chebyshev differentiation matrix)

matlab的m文件，计算复杂网络中节点的紧密中心性(closeness centrality of nodes in complex networks)

降低OFDM系统中PAPR的PTS改进算法—双层次相位法。可行。出CCDF比较图(Reduce the PAPR of OFDM system PTS improved algorithm- double the level of phase-based method. Feasible. Comparison of the CCDF)

本文是编程来实现中值滤波，从而达到图像去噪的目的(This is a program to achieve the median filter, so as to achieve the purpose of image denoising)

本程序仿真在给定系统延时下的QPSK系统误码率，其中没有使用成形滤波器，考虑了相位同步和符号同步，对工程人员很有参考价值(QPSK err rate simulation)
