I will post my code that i made, im a noob. just take my "||" as or in english, thats what i think of it, but it dont work, it only gives me 'NORTH' for any value please check and correct..It is m,y university assignment.

function[r]=direction(bearing)
if bearing == 0 || 360
 r= 0 || 360;
 printf('North\n')
elseif bearing== 90 || -270
 r= 90 || -120;
 printf('East\n')
elseif bearing== 180 || -180
 r= 180 || -180;
 printf('South\n')
elseif bearing== 270 || -90
 r= 270 || -90;
 printf('West\n')
else
 printf('Unknown Direction\n')
end

I found the solution, BTW thank you so much @paul and @ jos(10584)

   function[]=direction(bearing)
    if (bearing == 0 || bearing==360)
     disp('North\n')
    elseif (bearing== 90 || bearing ==-270)
     disp('East\n')
    elseif (bearing== 180 || bearing== -180)
     disp('South\n')
    elseif (bearing== 270 || bearing== -90)
     disp('West\n')
    else
     disp('Unknown Direction\n')
  end
  %it works fine

This should get you started:

    if A==1 || A == 2
       disp('A is 1 or 2') ;
    end

    if B == 1 && C == 2
       disp('B is 1 and C is 2') ;
    end

[Jos (10584)]

btw , the reason why you get 'North' all the time is because the condition

bearing == 0 || 360

is equal

bearing == 0 || true

which is always true of course.

function[r]=direction(bearing)

if bearing == 0 | | bearing==360

    r= 0; 
    fprintf('North\n')

elseif bearing== 90 | | bearing==-270;

    r= 90;
    fprintf('East\n')

elseif bearing== 180 | | bearing== 180;

    r= 180; 
    fprintf('South\n')

elseif bearing== 270 | | bearing== -90 ;

    r= 270; 
    fprintf('West\n') ;

else printf('Unknown Direction\n')

end

I think that's what you want unless you want to define r as a string ?
