MUSIC算法[1]是一种基于矩阵特征空间分解的方法。从几何角度讲，信号处理的观测空间可以分解为信号子空间和噪声子空间，显然这两个空间是正交的。信号子空间由阵列接收到的数据协方差矩阵中与信号对应的特征向量组成，噪声子空间则由协方差矩阵中所有最小特征值（噪声方差）对应的特征向量组成。(MUSIC algorithm [1] is a feature space based on matrix decomposition method. From the geometric point of view, the signal processing can be decomposed observation space the signal subspace and the noise subspace, it is clear that the two spaces are orthogonal. Signal Subspace data received by the array covariance matrix and eigenvectors corresponding to the signal component, the noise subspace from the covariance matrix of all the smallest eigenvalue (noise variance) eigenvector components.)

不同窗函数数下，自功率谱，互功率谱，频响函数和相干函数，绘制功率谱图(Not under the old function, since the power spectrum, cross-power spectrum, frequency response function and coherence function, map power spectrum)

这是我自己用MATLAB编的一个扫雷小游戏,程序比较经典,希望和大家一起分享.(This is for my own use MATLAB series of the game a small mine, the procedure is classic, want to share with everyone.)

本程序是有限时域差分源程序，有详细注解，方便学习理解。(This program is a limited time domain difference source program, has detailed notes, easy to learn to understand. )
