matlab程序，高阶谱分析，信号谱分析的方法一起就存在了，高价谱分析是当代信号处理的主要工具。--Matlab procedures, higher order spectral analysis, signal spectral analysis method in existence, high spectral analysis of contemporary signal processing major tools.

此程序为c++实现频谱分析，可用于对傅里叶变换进行分析-This procedure for the c++ to achieve spectral analysis, Fourier transform can be used to analyze
