How do I display R-squared and RMSE value for 2 curves while comparing?

I have 2 curves to plot-soundtemp_num and soundtemp_exp. These are data from a numerical optimization algorithm. I just want to display R-squared value and RMSE value in the same plot.

plot (timeexp,soundtemp_num,'b',timeexp,soundtemp_exp,'r');
