3. The determinant of a matrix A = [ai j ] can only be computed if it is a square matrix and A is reducible to U . 4. A square matrix A = [ai j ] is said to be singular if its determinant is zero. Otherwise, the matrix is nonsingular. A singular matrix is not reducible to U . 5. The inverse of a singular matrix does not exist, which implies that if A is nonsingular, then its inverse, or A−1 , exists. The determinant of matrix A, denoted by |A| or det(A), is computed in several different ways. By definition, the determinant is obtained by computing the cofactor matrix from the given matrix.
000 is the pivot element of the first row, and let m = ai1 /a11 for the rows i = 2, 3, 4. All elements in the second, 26 FUNDAMENTAL TOOLS FOR MATHEMATICAL COMPUTING third, and fourth rows are reduced to their corresponding values using the relationships ai j ← ai j − m *a1 j for columns j = 1, 2, 3, 4. 250 m = a41 /a22 , a4 j ← a4 j − m *a1 j Operations with Respect to the Second Row. 500 is the pivot element of the second row, and therefore, m = ai2 /a22 for the rows i = 3, 4. All elements in the third and fourth rows are reduced to their corresponding values using the relationships ai j ← ai j − m *a2 j for the columns j = 1, 2, 3, 4.
The fundamental tool in CFD simulation is the Navier–Stokes equation, which describes a single-phase fluid flow. Also, a set of ordinary or partial differential equations with their initial and boundary conditions is given. The solution to these problems makes use of the finite-difference method or finite-element methods, which reduces the problem to several systems of linear equations. Finite-Element Modeling The finite-element method is a numerical technique for evaluating things like stresses and displacements in mechanical objects and systems.
