spectrum.music对象和pmusic函数提供Schmidt提出的MUSIC算法。该算法基于对自相关矩阵的特征分析，用于对频谱的估计。这种谱分析将数据相关矩阵的信息分为信号子空间和噪声子空间。-spectrum.music objects and functions provide MUSIC algorithm pmusic Schmidt raised. The algorithm is based on the correlation matrix of the feature analysis, it is used to estimate the spectrum. Such spectral analysis information data correlation matrix into a signal subspace and noise subspace.
