摘要
考虑泛延拓矩阵的QR分解与广义逆,导出了泛延拓矩阵的QR分解与广义逆的公式,讨论了系统参数估计问题.结果显示所给方法既减少了计算量与存储量,又不会降低数值精度.同时推广和优化了文献[8,9]的研究结果,拓宽了实际应用领域的范围.
The author studied the QR factorization and generalized inverse of universal extended matrix.and the system parameter estimate is discussed.In addition,the formula of the QR factorization and generalized inverse of universal extended matrix were given.The results show that the algorithm is simple and fast,and it does not reduce the numerical accuracy.Another some results of paper[8,9] are generalized.
