Question

This is a matlab problem.

The heat index. HI (in degree s F). is an apparent temperature. For temperatures higher than 80& degree ;F and humidity higher than 40% it is calculated by: HI = C1 + c2T+ C3R + C4TR + C5T2 + C6R2 + C7T2R - C8TR2 + C9R2T2 where T is temperature in degree s F. R is the relative humidity in percent, C1 = -42.379. C2 = 2.04901523, C3 = 10.14333127 , C4 = -0.22475541. C5 = -6.83783 times 10 -3, C6 = -5.481717 times 10 -2, C7 = 1.22874 times 10 -3. C8 = 8.5282 times 10 -4, and C9 = -1.99 times 10 -6. Write a user-defined function for calculating HI for given T and R. For the function name and arguments use HI=HeatIn (T, R). The input arguments are T in & degree ;F and. R in %, and the output argument is HI in & degree ;F (rounded to the nearest integer). Use the function to determine the heat index for the following conditions: T = 95 degree F, R = 80%. T = 100 degree F, R = 100% (condition in a sauna).
