Determinant with row reduction
WebLet's find the determinant along this column right here. The determinant of b is going to be equal to a times the submatrix if you were to ignore a's row and column. a times the determinant of d, e, 0, f, and then minus 0 … WebSep 5, 2014 · This is also known as an upper triangular matrix. Calculating the determinant is simple from here and it doesn't matter what the size of the matrix is. The determinant is simply the product of the diagonal, in this case: a11 ⋅ a22 ⋅ a33 ⋅ a44. Remember that you can only calculate the determinant for square matrices. Answer link.
