Аннотация:In this paper, we prove that a 3ρ-locally maximum volume submatrix $\hat A \in \mathbb{R}^{r \times r}$ in the matrix $A \in \mathbb{R}^{M \times N}$ can be found in O(MNr(log r + log r / log ρ)) operations, and a ρ-locally maximum volume submatrix for ρ⩽3 can be found in O(MNr^3log r / log ρ) operations. Based on these submatrices, it is possible to construct a rank revealing LU decomposition with guarantees for the approximation accuracy in spectral and Chebyshev norms.
