Determinant with row reduction
WebSep 16, 2024 · Theorems 3.2.1, 3.2.2 and 3.2.4 illustrate how row operations affect the determinant of a matrix. In this section, we look at two examples where row operations are used to find the determinant of a large matrix. Recall that when working with large … Webdoes not change the condition of "no two in same row, no two in same column". So the patterns will be the same and signatures will be, so we can see that detA = detAT. Finding the determinant of A through row reduction: Let B be the matrix obtained from A by one row operation, so if the row operation is: swapping two rows, then detB = detA.
