A demonstration of the constraints renormalization method described in https://arxiv.org/abs/2212.03014
The main results in the paper (for 1D systems) were produced using the code in the folder spinChains_1D. The folder LTI_hierarchy_in_2D contains the code used for the 2D results in appendix B of the paper.
Implemented in MATLAB. YALMIP is required https://yalmip.github.io/
A matrix-free implementaion of the SCS solver for the 1D problem is in the SCSMF folder.
