求解一个方阵的的按模最大的特征值及相应的特征向量。-By solving a square of the largest eigenvalue model and the corresponding eigenvectors.

频率估计，用了最基本的Rife算法，和导数法。同时计算了平均频率和均方差值(Frequency estimation, using the most basic Rife algorithm and derivative method. The mean frequency and mean square difference are also calculated)
