MATLAB problem Would like a detailed answer line by line Ear

MATLAB problem. Would like a detailed answer line by line.

Early explorers often estimated altitude by measuring the temperature of boiling water. Write a script file that uses the following two equations to make a table that modern-day hikers could use for the same purpose. p = 29.921(1 - 6.8753 times 10^-6 h), T_b = 49.161 ln p + 44.932 where p is atmospheric pressure in inches of mercury, T_b is the boiling temperature in degree F, and h is the altitude in feet. The table should have two columns: the first is the altitude and the second is the boiling temperature. The altitude should go from -500 ft. to 10,000 ft. in increments of 500 ft Save the table results in an ASCII file called HW4Prob4. txt. b) Write another script file that does the following: Load the data saved in HW4Prob4. txt; Using the variable that contains the loaded data, assign the first column to a variable called Hloaded and the second column to a variable called Tloaded; Display these two variables in the Command Window without using the disp and fprintf functions.

Solution

Part a) Matlab code

p = @(h) 29.921*(1 - 6.8753*10^(-6)*h);% the pressure function
T = @(p) 49.161*log(p)+ 44.932; %the temperature function
fid = fopen(\'HW4Prob4.txt\',\'w\');
for h = -500:500:10000 % The height varies from -500 to 10000
   fprintf(fid,\'%d\\t%f\ \',h,T(p(h))); % Printing the values in the file
end

Result in HW4Prob4.txt

Part b)

load(\'HW4Prob4.txt\'); % loading the data in HW4Prob4.txt
format short g; % changing the display style format to short g
Hloaded = HW4Prob4(:,1); % copying the first column of HW4Prob4 to Hloaded
Tloaded = HW4Prob4(:,2); % Copying the second column of HW4Prob4 to Tloaded
{\'Altitude\',\'Boiling Temperature\';\'(ft)\',\'(degF)\'} % Dont put ; printing the heading
