One of the final exam problems in Linear Algebra Math 2568 at the Ohio State University. Math Forum - Ask Dr. Math 19/12/1996 · This matrix has the same determinant as A. Expanding by minors along the first column, we clearly see that the first three terms in column 1 will contribute 0 to the determinant, and so we have: det(A) = -(-1) det B = det(B) where B is the 3 x 3 determinant: 8 2 4 5 7 7 5 2 -6. (Notice that since the -1 appears in the 4th row of column 1, it has a negative sign in front of it in det(A)). Then (PDF) New Method to Compute the Determinant of …

To efficiently calculate the determinant of a matrix, we can first create zero entries, by doing row-operations that preserve the Determinant - Wikipedia For example, a matrix is often used to represent the coefficients in a system of linear equations, and the determinant can be used to solve those equations, although other methods of solution are much more computationally efficient. In linear algebra, a matrix (with entries in a field) is singular (not invertible) if and only if its determinant is zero. This leads to the use of determinants in
The determinant function uses an LU decomposition and the det function is simply a wrapper around a call to determinant. Often, computing the determinant is not what you should be doing to solve a given problem. Value. For det, the determinant of x. For determinant, a list with components 4.4 The Determinant and the Inverse of a Matrix 4.8 Set up a spreadsheet that computes the inverse of any three by three matrix with non-zero determinant, using this formula.
