For those who are wondering, this is unwrap in MATLAB:

 UNWRAP Unwrap phase angle.
    UNWRAP(P) unwraps radian phases P by changing absolute
    jumps greater than pi to their 2*pi complement. It unwraps
    along the first non-singleton dimension of P. P can be a
    scalar, vector, matrix, or N-D array.
 
    UNWRAP(P,TOL) uses a jump tolerance of TOL rather
    than the default TOL = pi.
 
    UNWRAP(P,[],DIM) unwraps along dimension DIM using the
    default tolerance. UNWRAP(P,TOL,DIM) uses a jump tolerance
    of TOL.
 
    See also ANGLE, ABS.


And I think the answer is no, but It would be nice...
