DEG180 is the jSphere module of jLab.

 DEG180  Converts degrees to the range [-180,180].
 
    [D1,D2,...,DN]=DEG180(D1,D2,...,DN) converts the input angles, which
    are measured in degrees, to the range [-180, 180].
 
    DEG180 also works if D1,D2,...,DN are cell arrays of numerical arrays.
 
    See also JDEG2RAD, JRAD2DEG, DEG180, DEGUNWRAP.
 
    'deg180 --t' runs a test.
