About QR Decomposition Calculator

A QR decomposition calculator that factors A = QR where Q is orthogonal (QᵀQ = I) and R is upper triangular. Uses classical Gram-Schmidt orthonormalization. Shows Q and R matrices. Verify QR = A and QᵀQ = I. Select from preset matrices. All calculations are client-side. Foundation for QR algorithm (eigenvalues).
