Normal atmospheric pressure is defined as 1 atmosphere [atm]. 1 [atm] = 14.6956 [psi] = 760 [torr] = 101.325 [kPa*].
1) Write a function, fn_psi2atm to convert psi to atm, torr and kPa. Set the output as 3 different unit with input of pressure in psi.
2) Write a script, to do the following work.
2-a. Read an external data Time Pressure.txt. by using fgetl, fscanf and textscan. You may combine those functions to read header lines separately, but do not use other functions to read the data.
2-b. Convert the pressure unit by using fn_psi2atm.
2-c. Use pressure unit of [atm]. Fit the data with linear and a third-degree polynomial by using polyfit. Use sprintf to store the fitted result.
2-d. Use subplot. In the first plotting area, plot time vs pressure in kPA unit. In the second plotting area, plot the data points in atm along w/ the fitted result.
Please use MATLAB to make the function & script with the given instructions.
