Most commonly, a time series is a sequence taken at successive equally spaced points in time. They are used to identify, model, and forecast patterns and behaviors in data that is sampled over discrete time intervals.

What I want is to resample the distance vector at regular time intervals (e.g. Anyone to lead me in the right direction please? Consider using timetables instead of timeseries objects, where you can store time-stamped data as column-oriented data variables. This MATLAB function resamples data such that the data is interpolated by a factor P and then decimated by a factor Q. Data must be sampled at equal time intervals. The resampled signal starts at the same value as x but is sampled with a spacing of len(x) / num * (spacing of x).Because a Fourier method is used, the signal is assumed to be periodic. Data must be sampled at equal time intervals. Learn more about resample . R. Resampling factor, such that R>1 results in decimation and R<1 results in interpolation..
