WebWe put matrices into reduced row echelon form by a series of elementary row operations. Our first goal is to show that each elementary row operation may be carried out using matrix multiplication. The matrix E = [ei, j] used in each case is almost an identity matrix. The product EA will carry out the corresponding elementary row operation on A. Webproduct of determinants, it is enough to show that detET = detE for any elementary matrix. Indeed, if E switches two rows, or if E multiplies a row by a constant, then E = ET, so …

Web(b) To produce 1.00 worth of output, Industry B requires 0.10 of its own product and 0.50 of Industry As product. Find D, the input-output matrix for this system. Then solve for the output matrix X in the equation X=DX+E, where E is the external demand matrix E=[40,00080,000]. WebFor example, if A is diagonalizable, then its powers A^n can be computed easily as A^n = PD^nP^(-1), where D^n is the diagonal matrix obtained by raising the diagonal entries of D to the n-th power. Not all matrices are diagonalizable, but many matrices encountered in practice are diagonalizable. lampe bureau sans fil ikea
