Explanation / Answer

%Save file as rainfall.m

%matlab-code that process rainfall of two cities

%a)

%jasper rainfall vector

jasper=[12.59 11.08 12.19 13.87 9.50 5.40 14.99 15.20 14.70 11.65 12.56 6.11];

%Clarkston rainfall vector

Clarkston=[10.80 8.01 4.98 8.65 6.05 4.76 9.02 4.31 8.56 7.45 4.22, 6.16];

%set jasperTotal =0

jasperTotal=0;

%set clarkstonTotal=0

clarkstonTotal=0;

%find total rainfall for two cities

for i=1:12

jasperTotal=jasperTotal+jasper(i);

clarkstonTotal=clarkstonTotal+Clarkston(i);

end

%find average rainfall for two cities

jasperavg=jasperTotal/12;

disp('Jasper averagea rain fall',jasperavg);

clarkstonavg=clarkstonTotal/12;

disp('Clarkston averagea rain fall',clarkstonavg);

%b)

%count cities that more than average for jasper and clarkston

avgcount1=0;

for i=1:12

if jasper(i)>jasperavg

avgcount1=avgcount1+1;

end

end

disp('Cities more than above average for city jasper ',avgcount1);

avgcount2=0;

for i=1:12

if Clarkston(i)>clarkstonavg

avgcount2=avgcount2+1;

end

end

disp('Cities more than above average for city Clarkston ',avgcount2);

%c)

%count number of cities that are lower than clarkston rainfall

lower=0;

for i=1:12

if jasper(i)<Clarkston(i)

lower=lower+1;

end

end

disp('Number of cities of jasper lower than rainfall of clarkston rainfall', lower);

----------------------------   ----------------------------   ---------------------------- ----------------------------

Sample output:

Jasper averagea rain fall
   11.6533
Clarkston averagea rain fall
    6.9142
Cities more than above average for city jasper
7
Cities more than above average for city Clarkston
6
Number of cities of jasper lower than rainfall of clarkston rainfall
1
