傅里叶函数变换求时间序列的非平均循环周期-Fourier function transforms the time series of non-average cycle

五对角矩阵追赶法求解矩阵，有调用方法，并且经过我优化，一次性将矩阵处理成五对角数列，减少循环次数-Pentadiagonal matrix chase method for solving the matrix, there is a method call, and after I optimized one-time matrix processing into PENTADIAGONAL series, reducing the number of cycles

循环谱的计算方法,能够运行出来的程序。仅供参考-The calculation method of cyclic spectrum, can run out of the application.For reference only
