Spectral-Clustering1

说明：  卫星二体轨道动力学模型仿真，用于卫星轨道模拟，航天领域(Satellite two-body orbit dynamics model simulation)

音频信号降采样程序 支持48k->8k 24k->8k 8k->1k 的降采样.实现方法,先做低通滤波,再做采样点抽取.低通滤波起使用67点FIR,系数由matlab使用窗函数法生成 (Audio signal down-sampling procedures to support the 48k-)

关于BPSK，QPSK，8QAM,16QAM，32QAM的调制解调程序。可作为单独模块加入到任何信道下，解调采用了两种方法。(On the BPSK, QPSK, 8QAM, 16QAM, 32QAM modulation demodulation process. As a separate module can be added to any channel, the demodulator uses two methods.)

对正交编码（Hadamard）+BPSK调制进行分析而用matlab进行仿真。(Hadamard code is a kind of error correcting code. )

很好用的几个matlab多目标视频跟踪的程序，有粒子滤波的，帧差法的等等，可以直接仿真运行(Good use of several multi-target video tracking matlab procedures, particle filter, frame difference method, etc., can be directly run the simulation)

本程序旨在计算在整个调节时段的初末水位已知的情况下（水位均为170米），从后往前计算出每个阶段的各个水位到最后阶段的最优发电效益，逐步向前递推找出最大年发电效益，从而找到最优化的路径放入到矩阵LJ中，本程序未考虑防洪限制。(The purpose of this procedure is to calculate the optimal power generation benefit for each stage from the rear to the final stage (the water level is 170m) in the case where the initial water level of the whole adjustment period is known (the water level is 170m), and the maximum annual power generation benefit can be found gradually forward. In order to find the optimized path into the matrix lj, the procedure does not take into account the flood control limitation.)

说明：  PSO算法，通用性较强，只要换一下fitness就可以了(PSO algorithm, universal strong, as long as a change in fitness can be a)

生成NURBS的曲线的Matlab源代码，用矩阵的方式实现。(Matlab source code about NURBS curve generation.)
