You actually want to wrap it, if I understand you correctly. You can use the mod or rem functions (choose a version) to wrap it:
phs = [0:10:1440];                      % ‘Unwrapped’ phase
phwrap = @(adeg) mod(adeg, 360+1E-8);   % Wrap Phase (mod)
phwrap = @(adeg) rem(adeg, 360+1E-8);   % Wrap Phase (rem)
wphas = phwrap(phs);
figure(1)                               % Plot The Result
plot(phs, wphas)
grid
If you want to ‘unwrap’ it, use the built-in MATLAB unwrap function.
