nterpolate data to a 5-minute time series in matlab

Assuming you have a time series data ts with timestamps as datetime values and corresponding values as double, you can interpolate the data to a 5-minute time interval by following these steps:

1. Set the datetime values as the time series object timestamp using the settimeseries method:

main.m
ts = settimeseries(ts, 'StartTime', ts.TimeInfo.StartDate);

2. Define a new time vector t for the interpolated time series with 5-minute intervals using the datetime function:

main.m
t = datetime(ts.TimeInfo.StartDate:minutes(5):ts.TimeInfo.EndDate)';

3. Interpolate the values of the original time series to the new time vector using the interp1 function:

main.m
x = interp1(ts.Time, ts.Data, t);
34 chars
2 lines

4. Create a new time series object with the interpolated values and the new time vector using the timeseries function:

main.m
ts_interp = timeseries(x, t);
30 chars
2 lines

Here is the complete code:

main.m
ts = settimeseries(ts, 'StartTime', ts.TimeInfo.StartDate);
t = datetime(ts.TimeInfo.StartDate:minutes(5):ts.TimeInfo.EndDate)';
x = interp1(ts.Time, ts.Data, t);
ts_interp = timeseries(x, t);
