A detailed description of elementary components of the experimental setup (like support computation, matrix rank computation, etc.) are furnished in numerical implementation details (PDF).
The scripts for generating Figures 1a and 1b are:
The two main scripts in this repository, used to generate Figures 5 and 6, respectively, are:
- srlasso_inexact_empirical_uniqueness_sufficiency_crosssection.py
- srlasso_inexact_empirical_uniqueness_sufficiency_experiment.py
The final figure was created using:
The supporting code for these scripts is distributed amongst:
