I have a phase plot in radians varying from 20 to 26 (a linear graph), how do i convert this plot from -pi to +pi or from 0 to 2 pi?

I have a phase plot in radians varying from values 20 to 26 (a linear graph) for a ring resonator , how do i convert this plot from -pi to +pi or from 0 to 2 pi?

[Voss]

phases = 20:26 % phases going from 20 to 26 radians

phases = 1×7

20 21 22 23 24 25 26

phases = mod(phases,2*pi) % the same phase values, now between 0 and 2 pi

phases = 1×7

1.1504 2.1504 3.1504 4.1504 5.1504 6.1504 0.8673

phases = phases - pi % the same phase values, now between -pi and +pi

phases = 1×7

-1.9911 -0.9911 0.0089 1.0089 2.0089 3.0089 -2.2743
