This subdirectory contains the following Matlab source codes and folders:

Alt_proj       - implementation of alternating projection for finding sparse solution of Ax = b.

DR_proj        - implementation of the DR splitting method for finding sparse solution of Ax = b.

DR_proj_raw    - implementation of the DR splitting method for minimizing the sum of indicator functions, 
                 as is normally considered in the literature.

Test_DR_alt
Test_DR_DR_raw - runcode.

Implementation and numerical experience with the above codes are described in the paper: 
    Guoyin Li and Ting Kei Pong
    "Douglas-Rachford splitting for nonconvex optimization with application to nonconvex feasibility problems",
    Submitted.
This code was last updated on March 27, 2015.

Questions/comments/suggestions about the codes are welcome.
