It is shown how to use some of the important properties of generalized reflexive (antireflexive) matrices to decompose linear least-squares problems whose coefficient matrices are generalized Reflexive into two smaller and independent subproblems. Expand. WebSolved Examples. Problem 1: Find if the given system of equations is consistent or inconsistent. x+3y = 5 and 2x + 6y = 8. Solution: Given, the system of equations are: x+3y = 5 and 2x + 6y = 8. As per the matrix equation, we know; AX = B. Hence, the system of equations can be written as: [ 1 3 2 6] [ x y] = [ 5 8]

WebA determinant is a property of a square matrix. The value of the determinant has many implications for the matrix. A determinant of 0 implies that the matrix is singular, and thus not invertible. A system of linear equations can be solved by creating a matrix out of the coefficients and taking the determinant; this method is called Cramer's ...
