stoch_subg_pwl_error.m  -- pwl subgrad method with errors in subgradients
stoch_subg_exp_pwl.m    -- minimize expected value of piecewise linear fct
stoch_subg_online_reg.m -- online regression example

Helper functions:
sgm_pwl_error_sqrsum.m      -- square summable step size with subgrad errors
stoch_subg_exp_pwl_sqrsum.m -- square summable step size for pwl stoch subgrad
