This subdirectory contains the following Matlab source codes:

condno_adm.m          The main code that minimizes condition number using ADM.

cond_update_X.m
cond_update_y.m       These codes solve the ADM subproblems by spectral projected gradient method.

handleMatrix.m        This code creates function handle for condno_adm.m

simplex_proj.m        This code computes the projection onto simplex.

condition_se_dual.m   This code writes input to SeDuMi for minimizing condition number.

cond_polytope_test.m  This is the run code.

Implementation and numerical experience with the above codes are described in the paper:
