MATLAB: I need the angles in the [-pi:pi] range instead of [0:2*pi]

Question

I have an angle in degrees, 225 degrees. Now degtorad(225) function gives me:

>>degtorad(225)

ans =

    3.9270 radians

above 'ans' is in the range 0:2pi

I want to know the procedure that i get an answer in the range -pi:pi, as 225 degrees is also equal to -2.3562 radians

 225 degree=3.9270 rad
 225 degree=-2.3562 rad.

I hope I have made my point clear.

Thank you in advance.

Answer 1

R(R > pi) = R(R > pi) - 2*pi;
