摘要
研究一类基于中值逼近的正交秩1矩阵追踪算法,在整个算法的过程中,迭代矩阵保持了Toeplitz结构,确保了较少的奇异值分解时间,通过数值实验说明了新算法比正交秩1矩阵追踪算法与经济正交秩1矩阵追踪算法有更高的精确度.
A kind of orthogonal rank 1 matrix tracking algorithm based on median approximation is studied. In the process of the entire algorithm,the iterative matrix maintains its structure ,makes less singular value decomposition time. Finally, it is shown through the numerical experiment that the new algorithm has higher accuracy than the orthogonal rank 1 matrix tracking algorithm and the economic orthogonal rank 1 matrix tracking algorithm.
