ARK Reproducible code

First step: Download cvx from http://cvxr.com/cvx/. Get into cvx toolbox and setup cvx by running cvx_setup.m

Second step: Just run ARK_simulation.m in Matlab

For the first time simulation, all .mat files except GroundTruth.mat file in ARK directory can be removed. In that case the ARK_simulation code will generate system matrices data for SEK method. 
To save execution time, you may not remove any .mat file.
