I am not sure how to go about this question. Any help will be greatly appreciated. Write a function quadrant that receives two arguments, which are a pair of (X, Y) coordinates, and returns the corresponding quadrant in roman numerals (i.e. I-IV), for example,>> fprintf('Input coordinates will be in quadrant %s.\n',quadrant(3,4)) Input coordinates will be in quadrant I.

Hint: See if you can convert the logicals x>=0 and y>=0 into numbers from one to four in accordance with the quadrant. Is really is easy to do.

在 MATLAB Online 中打开

x=4;y=-7; %test value
switch true 
case x >=0 && y>0
disp('Quadrant I') 
case x <=0 && y>0
disp('Quadrant II') 
case x <=0 && y<0
disp('Quadrant III') 
case x >=0 && y<0
disp('Quadrant IV') 
otherwise 
disp('Origin') 
end
