Although you think, that the "error" is obvious, it is not exactly defined, how it could be "corrected". If this is e.g. a measurement, this might be the important peak, while the low frequency sine wave is the noise. So please explain exactly, what you want to achieve.

If you just wanted to bludgeon your dependent variable vector (here ‘D0’) into compliance, keep the original independent variable vector (for example naming it ‘T0’), delete points 500:503 from both your independent and dependent vectors (perhaps naming the vectors with deleted values ‘T1’ and ‘D1’ respectively), then use interp1 with a nonlinear interpolation method (such as pchip or spline) to create your new ‘patched’ dependent variable vector, ‘D2’:
D2 = interp1(T1, D1, T0, 'spline');
That could work. No promises.
