Hi,
first of all, if you apply the simulator for research (academic purpose), please consider to get a free academic license which gives you access to the latest release, which is v1.6.
Further, depending on what you are aiming to simulate, I highly recommend to consider our much newer 5G Link Level Simulator.
Still, to plot results after simulation in the LTE-A Uplink simulator, you may consider to use the line
LTE_UL_plot_results( simulation_results, LTE_params);
from the very end of LTE_UL_sim_main_single.m. I hope that helps.
best
Stefan
