Fixed-point algorithms for frequency estimation and structured low rank approximation
Fredrik Andersson, Marcus Carlsson
We develop fixed-point algorithms for the approximation of structured matrices with rank penalties. In particular we use these fixed-point algorithms for making approximations by s…
