Unwrap radian phases by adding or subtracting multiples of 2*pi.
B = unwrap(X) B = unwrap(X, TOL) B = unwrap(X, TOL, DIM)
This function unwraps radian phases by adding or subtracting multiples of 2*pi as appropriate to remove jumps greater than TOL.
TOL defaults to pi.
Unwrap will work along the dimension DIM. If DIM is unspecified it defaults to the first non-singleton dimension.
