The cofactor matrix of a square matrix M of size n, also called comatrix and noted com (M), is a square matrix of size n defined as follows : We note c (i, j) the element in row i and column j of the comatrix. Then, c(i,j) = ( โ 1)i+jdet(M (i,j)) c ( i, j) = ( - 1) i + j det ( M ( i, j)), where 'det' represents the determinant.
