Web24 sep. 2016 · Assume we plan to solve a least square problem, A x = b, as follow: - A is m × n vandermonde matrix. The entries are populated using m value between 0 to 1 (given as input). -The corresponding vector b calculated using an original function that we would like to estimate. - compute SVD using A = U Σ V ∗. - compute U ∗ b. - Solve Σ w = U ... Web1 mrt. 2024 · 1. Lets call your big m × n matrix A. Then for the composition Q R = A, you have a m × m matrix Q and a m × n matrix R. This seems to be way to big to store, but: R has the form ( R ~ 0) where R ~ is an (upper triangular) n × n matrix (which is small in your example). Q is huge, but does not need to be stored explicitly.
