Question

Write a program in MATLAB that:

i) Creates a two-dimensional array A whose first column will contain degrees of temperature from 0 to 100 per 5 degrees Celsius (0, 5, 10, 15, ..., 100), while the second
column will contain the corresponding degrees in Fahrenheit , 41, 50, ..., 212).
ii) Calculates the average temperature in degrees Celsius and Fahrenheit of array A and store the averages in a one-dimensional array B.
iii) Displays in the Command Window: a) array A with disp, and b) the values of array B with fprintf to display the following message:
Mean temperature is 50 Celcius or 122 Fahrenheit.

The relationship between temperatures in degrees Celsius and Fahrenheit is as follows: F=9/5C+32 where C is the temperature in degrees Celsius and F in Fahrenheit.

Explanation / Answer

% part (i)

A = zeros( 21 , 2 );

index = 1;

% initialize the first colum

for i = 0 : 5 : 100

    A(index, 1) = i;

    index = index + 1;

end

index = 1;

% initialize the first colum

for i = 41 : 9 : 221

    A(index, 2) = i;

    index = index + 1;

end

% part (ii)

B = [ 0 , 0 ];

sum_F = 0;

sum_C = 0;

% get the rows and columns

[ r , c ] = size(A);

for i = 1 : r

    sum_C = sum_C + A( i , 1 );

    sum_F = sum_F + A( i , 2 );

end

% calculate the averages

average_C = sum_C / r;

% calculate the averages

average_F = sum_F / r;

B = [ average_C , average_F ];

% part (iii)

fprintf('A ... ');

% Displays in the Command Window: a) array A with disp

disp(A);

fprintf(' B ... ');

fprintf('Mean temperature is %d or %d Fahrenheit. ', B(1), B(2));
