Nettet15. apr. 2024 · 3. For the underdetermined system A·x = b you can compute the null space of your coefficient matrix A. The null space, Z, is a set of basis vectors spanning a subspace of A such that A·Z = 0. In other words, the columns of Z are vectors that are orthogonal to all of the rows in A. This means that for any solution x' to A·x = b, then x' … Nettet29. okt. 2009 · In this paper, we show that Sudoku puzzles can be formulated and solved as a sparse linear system of equations.
