Faraz,
If you create folders called "Plots" and "STL" then the error will go away. The error is due to matlab not finding those folders on your computer.

I have tried, even after downloading surf2stl, but gets the following message

??? Error using ==> print at 364
Cannot create output file 'Plots\surf2solid_polar_ex.png'

Error in ==> surf2solid_polar_ex at 23
print('-dpng', 'Plots/surf2solid_polar_ex.png');

Thank u

I need help.
I have the data for which mu_est, sigma_est and p_est is NaN. I do not know what to do.
