中文说明：基于matlab GUI界面设计,对于初学者具有参考意义，esprit算法对有干扰的信号频率进行估计,旋转机械二维全息谱计算，matlab实现了五类灰色关联度模型的计算,最终的权值矩阵就是滤波器的系数。
English Description：
Based on Matlab GUI interface design, for beginners has reference significance, ESPRIT algorithm is used to estimate the interference signal frequency, rotating machinery two-dimensional holographic spectrum calculation, matlab calculation of five gray correlation model, the final weight matrix is that of the filter.
