Supports real-valued … Web25 Mar 2024 · The Sherman–Morrison formula suggests a computational shortcut to update a matrix inverse subject to a rank-one update, i.e., an additive change of the form A + u v ⊤ where u, v ∈ R n: ( A + u v ⊤) − 1. Suppose we have precomputed B = A − 1, the shortcut is. ( A + u v ⊤) − 1 = B − 1 1 + v ⊤ B u B u v ⊤ B. Implemented ...
