I've already created the code needed for this part:

%Part A
clear all; clc; 
tempdata = fopen('rec0506a.dat','r') ;
fgetl(tempdata); 
fgetl(tempdata);   
T = fscanf(tempdata, '%*f%f%f%f ',[3,inf])';
fclose(tempdata);
%Part B (means)
clc;
format shortg
sensormean= mean(T) ;
hourlymean = mean(T')' ;
%Part C (Table)
clc;
overallmean = (mean(sensormean) + mean(hourlymean))./2;
t = 1:8;
fprintf('hour     T1        T2         T3  |   means \n-------------------------------------------------  \n')
fprintf('%2d    %5d      %4d         %1d  |   %4.1f  \n',[t',T,hourlymean]')    
fprintf('--------------------------------------------------- \n')
fprintf('means = %2.1f  %8.1f   %7.1f  | %6.1f \n',[sensormean,overallmean]')

How exactly do I do this part though? It's confusing me.

D) Open a new file for writing, say rec0506b.dat. Using again at most five fprintf commands, save the above table of Part (c) in the new file, then close the file and upload it on sakai together with the rest of your recitation work.
