7.7 MATLAB: QR Factorization LAB 7.7.1: MATLAB: QR Factorization This tool is provided by a third party. Though your activity may be ACTIVITY recorded, a page refresh may be needed to fill the banner. 0 / 1 MATLAB: QR Factorization In this activity you will find the QR factorization of a matrix. Consider the matrix A. 4 = Use the qr( ) command to find the QR factorization of A, where Q is an orthogonal matrix band R is an upper triangular matrix. A = [-2 0 3; 1 3 1; 0 1 -1] [Q, RJ = qr(A) Verify QR=A. checkA = Q*R Use the following matrix for this activity. 3= -2 1 0 5 Script Save C Reset MATLAB Documentation 1 Enter the matrix B. Then use the qr( ) command to find the QR factorization of B, storing 2 %the orthogonal matrix in QB and the upper triangular matrix in RB. Note that while the focus 3 %of the last section of the zyBook was on square matrices, QR factorization can be done for 4 %any size matrix. Verify the result. Find the product of QB and RB, storing it in checkB. This matrix should CO 7 %equal the original matrix B. Run Script ? Trouble with lab?
