Question
CAS EXPERIMENT. QR-Method. Try to find out experimentally on what properties of a matrix the speed of decrease of off-diagonal entries in the QR-method depends. For this purpose write a program that first tridiagonalizes and then does QR-steps. Try the program out on the matrices in Probs. 1. 3. and 4. Summarize your findings in a short report.
Solution
The first step in solving 20.9 problem number 10 trying to solve the problem we have to refer to the textbook question: CAS EXPERIMENT. QR-Method. Try to find out experimentally on what properties of a matrix the speed of decrease of off-diagonal entries in the QR-method depends. For this purpose write a program that first tridiagonalizes and then does QR-steps. Try the program out on the matrices in Probs. 1. 3. and 4. Summarize your findings in a short report.
From the textbook chapter Tridiagonalization and QR-Factorization you will find a few key concepts needed to solve this.
