The matrix permanent is sadly more computationally intensive than the determinant, which can be computed using an O (n^3) algorithm based on an LU factorization of the matrix. Below is some code I wrote a few years ago to compute the matrix permanent.

WebMar 24, 2024 · Determinants are mathematical objects that are very useful in the analysis and solution of systems of linear equations. As shown by Cramer's rule, a nonhomogeneous system of linear equations has a unique solution iff the determinant of the system's matrix is nonzero (i.e., the matrix is nonsingular). For example, eliminating x, y, and z from the … In linear algebra, the computation of the permanent of a matrix is a problem that is thought to be more difficult than the computation of the determinant of a matrix despite the apparent similarity of the definitions. The permanent is defined similarly to the determinant, as a sum of products of sets of matrix entries that lie in distinct rows and columns. However, where the determinant weights each of th…

WebFor 0/1 matrices, the matrix A can be thought of as the adjacency matrix of a bipar-tite graph (technically, A is an of-diagonal block of the adjacency matrix), and then the permanent counts the number of perfect matchings. Computing the permanent of integer matrices can be reduced in polynomial time to that of computing the permanent of 0/1 ...
