Let a = [1 0 − 1 2 1 − 2 0 − 1 2]. Finally, the elementary matrix so corresponds to interchanging row i and row j is a permutation grid for a permutation with an odd count of inversions. Web d = ⎡⎣⎢⎢⎢1 0 0 0 2 −3 0 0 3 −8 11 14 4 −13 22 −17⎤⎦⎥⎥⎥ d = [ 1 2 3 4 0 − 3 − 8 − 13 0 0 11 22 0 0 14 − 17] hence, det(a) = (−13) det(c) = (13) det(d) det ( a) = ( − 1 3) det ( c) = ( 1 3) det ( d) you could do more row operations or you could note that this can be easily expanded along the first column. Web here you can calculate a determinant of a matrix with complex numbers online for free with a very detailed solution. Hence, its determinant is − 1. Web in reduced row echelon form you usually have to divide rows in order to get those leading 1's. Web this page allows to find the determinant of a matrix using row reduction, expansion by minors, or leibniz formula. Web can you find the determinants of a matrix given its row echelon shape?

When you divide a row the determinant will also be divided and thus will change.
