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