===Testing performance===
<br>
Run serial and parallel(using the above method) versions of msmf_corr_coeff.m. With profiling, the parallel version takes much longer time than the serial one. On a closer inspection, a single call to gurobi takes a very small amount of time. Using parfor will probably not give us any benefit. However, I suspect that for large R (~1000) we will see improvements from parallelism. <br>

====Testing instance 1====
We used the following parameters to have a small-size problem:
K = 1, S = 2, industry = 4, monte_N = 1, monte_M = 2. quota_per_up = 1, mktsize = 3, n_trail = 2, '''R = 1000''', ini_w_M = 10, n_cores = 12.

The parallel version now is ~3.5 time faster than the serial version. I believe it might be even faster with more cores. However I do not completely understand how the computation time scales with R (and other parameters). Will run another test with R = 200.
