Problem 1 (20 Points): while loop
After studying Example 9.3 (P. 323) – this is the problem to convert units from radians to degrees – create a single m-file that produces two tables:
(a) The first table considers the range of angles between 5 and 180 deg with an increment of 5 deg. Notice that you should still end up with a matrix containing 36 rows.
(b) The second table considers angles between 10 and 180 deg with an increment of 10 deg. Notice that, this time, you will end up with a matrix containing 18 rows.
Submission: 1 m-file and a printout of the command window.
Explanation / Answer
%matlab code
%part (a)
degree = linspace(5,180,36);
matrix = zeros(length(degree),2);
for i=1:36
matrix(i,1) = degree(i);
matrix(i,2) = (degree(i)*pi)/180;
end
disp(matrix);
