Hello, i have a data of time series. I want to get these data on regular time intervals (each 15 min). How I can achieve this task under matlab?

If you have a new enough version of MATLAB, you can use a timetable() and use retime()

Your image appears to be using timetable objects; your original question asked about time series. If you do have timeseries objects, you can use the resample() method.

Thanks Roberson for your help. In fact the command that i needed was

resample(timeSeries.Variables,1,15);

since i had the data every 15 minutes.

Use interp1() to resample the data at the desired interval.

OK. But It's hard for anyone to give you specific recommendations or code when you don't even show us what form your data is in. So why don't you just resample all your vectors so that they cover the same time intervals, add them up, and divide by the number of vectors. Will that not work?

Hi Image Analyst. this is not complicate enough as you say. But the function interp1 () does not work for my series that you find enclosed a screenshot.
