Matrix inversion sums

Web15 mrt. 2024 · Assume that the matrix C is invertible. Then the sum of all entries of its inverse C^ {-1} is \sum _ {k=1}^ {n}x_ {k}+\sum _ {k=1} ^ {n}y_ {k}. A natural, yet laborious, approach to proving this theorem is to compute the entries of C^ {-1} using ( 1) and then to sum them. The resulting sum can be seen (by a tricky induction) to simplify to \sum ...
