Matlab syntax. >> [Q,R] = qr(A,0); % A is a mxn matrix, Q is mxn orthogonal, R is nxn upper triangular. Example: QR decomposition of a 4x6 matrix. The optimal scanning distance from a QR code is a 10:1 ratio of distance to width. For example, if the QR code is 2” wide, the optimal scanning distance is 20” away. QR codes are good at accommodating scanning distances near the optimal ratio, though. Scan the QR code to test its functionality at—and near—the 10:1 distance ratio.QR decomposition has following formula: A = QR, where: A is original matrix we want to decompose. Q is orthogonal matrix. R is upper triangular matrix. Main goal is rather simple, decompose matrix into matrices Q and R. To find a orthogonal matrix Q, we could used Gram-Schmidt process. This process takes input matrix and makes …QR decomposition writteninmatrixform: A = QR ,whereA 2 R m n,Q 2 R m n,R 2 R n: a 1 a 2 a n | {z } A = q 1 q 2 q n | {z } Q 2 6 6 4 r 11 r 12 r 1 n 0 r 22 r 2 n 0 0 r nn 3 7 7 5 | {z } R I Q TQ = I ,andR isuppertriangular&invertible I calledQR decomposition (orfactorization)ofA I usually computed using a variation on Gram-Schmidt procedure which is less sensitive …ä Result of Householder QR: Q 1 and R 1 such that Q 1R 1 = X.
