这是用matlab语言编写的骨架提取法，比较基础，适合基础学习者使用(this is gujiatiqufa made by matlab)

说明：  MUSIC方法是Schmidt 在 1979 年首先提出的,并于1986 年重新发表。该方法和 Roy 于1986 年提出的 Esprit方法都是早期经典的超分辨率 DOA 估计方法 即超瑞利限的方法 ,他们同属特征结构的子空间方法。(MUSIC method is Schmidt first proposed in 1979, and re-released in 1986. The method and Roy in 1986, Esprit proposed methods are early classic super-resolution DOA estimation method that is super-Rayleigh limit of the method, they belong to the same characteristic structure of the subspace method.)
