Need detail comments so I can understand whats happening

29. The heat ity, is the apparent temperature felt by the body. An National Weather Service for calculating the HI is given by: index HI, calculated from the air temperature and relative humid- equation used by the 42.379+2.04901523T +10.14333127R-0.22475541TR-6.8378310 -5.48 1717 10-2R" + 1.22874 x 10-3T2R + 8.5282 10-4TR-1.99 x10-6T2R" where Tis the temperature in?F, and R s the relative humidity in integer percentage. Write a MATLAB program in a script file that displays the fol- lowing chart of heat index for given air temperature and relative humidity in x 10-31
