Question

Arrays: City temperatures The maximum daily temperatures (in "C) for Istanbul and Ankara during August 2019 are given below. Ankara: [33 30 31 32 33 35 30 29 29 28 29 30 32 32 33 32 34 31 33 30 29 30 31 33 31 30 27 26 27 26 27] Istanbul: [35 32 32 31 34 30 29 32 34 35 36 35 34 32 33 33 34 35 35 34 32 30 30 29 28 31 32 30 32 32 29] For your convenience, these values are stored in a MATLAB variable file named HwO6citytemp.mat. Place the file in your MATLAB work folder. Now you can get the values into their arrays t_Ank and t_Ist by issuing the following command in your homework m-file: load Hw06citytemp Write a MATLAB program that evaluates and displays the following information all x should be replaced by the values your program evaluates): The monthly max temperature for Ankara is: x The monthly max temperature for Istanbul is: x For x days the max temperature was above average in Ankara. For x days the max temperature was above average in Istanbul. On the following x days of the month, Ankara had lower max temperatures than Istanbul 1 23x... On the following x days of the month, Istanbul had lower max temperatures than Ankara: 4 6 7x... On the following x days of the month, max temperatures were the same in both cities: 14 15 17 x... Make your program as structured as possible. Remember to include comments in it. Never use the commands BREAK, CONTINUE or RETURN.

Answer 1

%t_Ank = [33,30,31,32,33,35,30,29,29,28,29,30,32,32,33,32,34,31,33,30,29,30,31,33,31,30,27,26,27,26,27];
%t_Ist = [35,32,32,31,34,30,29,32,34,35,36,35,34,32,33,33,34,35,35,34,32,30,30,29,28,31,32,30,32,32,29];

%finding mean of the data provided
mean_Ank = mean(t_Ank);
mean_Ist = mean(t_Ist);

%finding maxium of the data provided
max_Ank = max(t_Ank);
max_Ist = max(t_Ist);

fprintf('The monthly max temperature for Ankara is: %f \n',max_Ank);
fprintf('The monthly max temperature for Istanbul is: %f \n',max_Ist);

%create array of 1s and 0s for condition temperature above average and find
%the sum of all the 1s to count the days.
fprintf('For %d days the max temperature was above average in Ankara.\n',sum(t_Ank>mean_Ank));
fprintf('For %d days the max temperature was above average in Istanbul.\n',sum(t_Ist>mean_Ist));

%max temperature of Ankara < max temperature of Istanbul vector
t_AnkLTht_Ist = [];
%max temperature of Ankara > max temperature of Istanbul vector
t_AnkGTt_Ist=[];
%max temperature of Ankara = max temperature of Istanbul vector
t_AnkEQt_Ist =[];

%loop expects size of t_Ist & t_Ank to be same
if(size(t_Ank)==size(t_Ist))
for i=1:length(t_Ank)
if(t_Ank(i) < t_Ist(i))
t_AnkLTht_Ist = [t_AnkLTht_Ist i];
elseif (t_Ank(i) > t_Ist(i))
t_AnkGTt_Ist = [t_AnkGTt_Ist i];
else
t_AnkEQt_Ist = [t_AnkEQt_Ist i];
end
end
fprintf('On the following %d days of the month,\n',length(t_AnkLTht_Ist));
fprintf('Ankara had lower max temperatures than Instanbul:\n');
disp(t_AnkLTht_Ist)
  
fprintf('On the following %d days of the month,\n',length(t_AnkGTt_Ist));
fprintf('Instabul had lower max temperatures than Ankara:\n');
disp(t_AnkGTt_Ist)
  
fprintf('On the following %d days of the month,\n',length(t_AnkEQt_Ist));
fprintf('Max temperatures were the same in both cities:\n');
disp(t_AnkEQt_Ist)
end

Output:

>> test The monthly max temperature for Ankara is: 35.000000 The monthly max temperature for Istanbul is: 36.000000 For 15 days the max temperature was above average in Ankara. For 13 days the max temperature was above average in Istanbul. On the following 21 days of the month, Ankara had lower max temperatures than Instanbul: Columns 1 through 11 1 2 3 5 8 9 10 11 12 13 16 Columns 12 through 21 18 19 20 21 26 27 28 29 30 31 On the following 6 days of the month, Instabul had lower max temperatures than Ankara: 4 6 7 23 24 25 On the following 4 days of the month, Max temperatures were the same in both cities: 14 15 17 22

Before running the code you have to perform the steps provided in the question to load the data from HW06citytemp.data. Or you can uncomment the variables I have defined.

Give thumbs for the solution if you found it helpful.
