PALM Code solves the following problems: min ||x||_1 + ||e||_1 s.t. b = Ax+e ================================ Two methods to make: (1) In matlab: mex -I -lmwblas -lmwlapack -DCOMPILE_MEX -DBLAS_IMPLEMENTATION_MATLAB -DCOMPILE_MEX (2) Using g++ (in the Makefile) Currently, there exist wrappers for the BLAS/LAPACK libraries for the ACML and MATLAB libraries. to use them, in the Makefile, add -DBLAS_IMPLEMENTATION_ to the compile commands Be sure to also include the header and library files for the corresponding libraries. Notes: (1) MATLAB libraries use a subset of Intel MKL's libraries, which are optimized for Intel Processors and can utilize multiple cores, unlike ACML libraries. I didn't write wrappers for the MKL libraries, but to increase performance, the user may want to use Intel MKL's libraries. (2) ACML libraries do NOT exist for Mac OSX ================================ test.m, test_random.cpp are just scripts to verify the output of the code in matlab and in C ================================ Email of Authors: Allen Yang: yang@eecs.berkeley.edu Victor Shia: vshia@eecs.berkeley.edu
