%To solve optimization problem:
%Create a new subfolder in ...\PSG\MATLAB:
%..\PSG\MATLAB\problem_LOGEXPSUM_MaxLikelihood
%Download and unpack the following zipped file from 'Data' to the created folder:
%'Mat_data_problem_LOGEXPSUM_MaxLikelihood.zip'
%Run program 'problem_LOGEXPSUM_MaxLikelihood.m'
%=======================================================================

clc;

%Load data:
load('.\problem_LOGEXPSUM_MaxLikelihood_data.mat')

%Solve optimization problems:
[xout, fval, status, output] = riskprog({-1,'logexp_sum'}, [], H, c, [], [], [], [], [], [], lb, ub);

%Display results:
