摘要
由于矩阵的奇异值具备的一些良好性质,它在许多领域得到了非常广泛的应用。但是由于传统的矩阵奇异值求解方法很难得到良好的结果,这就给奇异值的实际应用带来了不小的难度。本文采用抽样估计的方法估计大规模矩阵的奇异值,探索一种求解大矩阵奇异值的方法。
Thanks sometime,tradition to the good method for speciality ,matrix's singular value has been used in a very large scopes.but matrix's singular value compute is difficult to get a nice result.This paper consideres to use a new method named randomly selected samples method to estimate the large matrix's singular value.
