This paper introduces a mathematical method Power Algorithm, which is used to calculate maximum eigen value and corresponding eigenvector of a matrix. In attribute analysis, some conventional technologies such as the third generation Coherence Algorithm and multi attribute weighted comprehensive parameter method, are based on the analysis of covariance matrix eigen structure. Analyzing the procedure of processing algorithm, we found out that they only need computation of maximum eigen value and corresponding eigenvector. To improve computation efficiency, we replace the traditional Jacob method by this Power Algorithm, which reduces largely calculating time without losing accuracy.
