数学建模十大经典算法，希望各位喜欢。请多多支持，多多下载！(Ten classical algorithm of mathematical modeling, I hope you like. Please support, a lot of downloads!)

经典MUSIC算法，只针对非相干空间信号源，原理课参考张贤达版的现代信号处理。(failed to translate)

说明：  实现雅可比叠代算法 在matlab中 输入矩阵A,b, 初值x 调用该函数 得到结果(achieve Jacobi iterative algorithm in Matlab input matrix A, b, x initial function to be called the results)

模拟天气雷达接收到的含有噪声的降水信号，并提出了对收到的离散回波信号进行估计分析的改进的PPP法的仿真程序(The weather radar simulation received containing noises precipitation signal, and proposed to the discrete received echo signal analysis estimates of the improvement of the PPP method simulation program )

Only coding parameters of sound generation model • LPC is an example where parameters are a1, a2, …ak , e(n) • Music instrument parameters: pitch, loudness, timbre, …Frequency Masking: If a tone of a certain frequency and amplitude is present, then other tones or noise of similar frequency cannot be heard by the human ear • the louder tone (masker) makes the softer tone The Masking Threshold is used by the audio encoder to determine the maximum allowable quantization noise at each frequency to minimize noise perceptibility: remove parts of signal that we cannot perceive

prim算法的matlab，很好用~非常适合在图论中的应用~(the krusk algorithm matlab, very easy to use- very suitable for application in Graph Theory ~)
