Matlab functions

• SURE for SVT: sure_svt.m

• Divergence for SVT: div_svt.m

• SURE for spectral estimators: sure_spec_fun.m

• Divergence for spectral estimators: div_spec_fun.m

Matlab scripts

We provide the Matlab scripts that generate the figures and movies in the paper and in the website, along with the source data required to run them. For convenience, in some cases we also provide the precomputed data to directly generate the figures and movies.

• Script to generate Figure 1: demo_sure_vs_montecarlo.m

  • Requires SURE for SVT

  • Precomputed data: data_sure_vs_montecarlo.mat

• Script to generate Figure 3: generateFig3.m

  • Requires divergence for SVT

  • Source data: aperiodic_pincat2.mat

• Script to generate Figure 4: generateFig4.m

  • Requires divergence for SVT

  • Source data: aperiodic_pincat2.mat
