1. The problem statement, all variables and given/known data I need to understand how I would go about using QR decomposition of a matrix to find the matrix's eigenvalues. I know how to find the factorization, just stuck on how I would use that factorization to find the eigenvalues. 2. Relevant equations A=QR where Q is an orthogonal matrix such that Qtranspose = Qinverse 3. The attempt at a solution det(λ*I - QR) = 0? this doesn't really help.
