When I lookfor phase the result is
phase Computes the phase of a complex vector PHI=phase(G)
G is a complex-valued row vector and PHI is returned as its phase (in radians), with an effort made to keep it continuous over the pi-borders.
This implies that the output of the method is unwrapped but if I try unwrap(phase(PHI)),
the output becomes different. Why is that? Does not phase already return unwrapped phase?
Note: phase is in the System Identification Toolbox
The phasecommand is not found in the MATLAB Documentation. Just shows up with lookfor phase
