This subdirectory contains the following Matlab source codes:

runcode_DIRL_bian.m      Runcode. Can be run directly. One needs to install SPGL1 for the runcode to work.

ADMM_CS_LY_S.m           Implementation of ADMM for the subproblem with weighted l1 objective and weighted least squares constraint

SCP_log_LL2.m            Implementation of SCP_ls for minimizing log penalty subject to Lorentzian norm constraint

logpen.m
Lorentzian.m             Subroutines for runcode

CaseSg.m         
SubP_alpha.m             Subroutine for SCP_log_LL2

Implementation and numerical experience with the above codes are described in the paper: 
    Shuqin Sun and Ting Kei Pong
    "Doubly iteratively reweighted algorithm for constrained compressed sensing models",
    Submitted.
This code was last updated on June 16, 2022.

Questions/comments/suggestions about the codes are welcome.
