这是在AR模型的功率谱估计，对比经典谱估计有明显的优点，是一种新的估计。(This is the AR model of the power spectrum estimation, contrast classical spectrum estimation has obvious advantages, is a new estimate.)

此例要求供应中心到最远需求点的距离尽可能小(This case requires the demand supply center to the farthest point distance as small as possible)

关于共振峰提取的程序，已调试过，可以使用，欢迎交流借鉴。(Formant extraction procedures, debugging, you can use, welcomed the exchange learn.)

张德丰matlab小波分析源代码，从信号时-频联合分析引入小波变换，将信号的多分辨率分析及Mallat算法作为全书的重点，并在此基础上，进一步阐述了双正交小波多分辨率分析、小波包多分辨率分析、提升小波应用，还讲述了小波分析在奇异性检测、去噪及数据压缩中的应用。 (Zhang Defeng matlab wavelet analysis source code)
