Factors a rank-`r` matrix into `{C, F}`, where `C` holds the pivot columns and
RankDecomposition[m]
RankDecomposition[{{1, 2}, {2, 4}}]
→ {{{1}, {2}}, {{1, 2}}}RankDecomposition[{{1, 2, 3}, {4, 5, 6}}]
→ {{{1, 2}, {4, 5}}, {{1, 0, -1}, {0, 1, 2}}}- Method — default Automatic
- Modulus — default 0
- Tolerance — default Automatic
