Introduction Some useful syntax in MATLAB: A = AB A T A -1 QR factorization of A QR factorization with permutation A = [ ; ; ] A*B A’ inv(A) [Q,R] = qr(A) [Q,R,E] = qr(A)

7
Introduction Some useful syntax in Excel: Suppose A = (cells A1:B2) B = (cells D1:E2) Then AB AT A-1 MMULT(A1:B2, D1:E2) TRANSPOSE(A1:B2) MINVERSE(A1:B2)

8
Introduction AB = C In order to calculate C and place it in cells G1:H2: 1)Highlight cells G1:H2 2)Type “= MMULT(A1:B2, D1:E2)” 3)Press Control, Shift and Enter simultaneously A (2x2), B (2x2) C (2x2)
