Interpolate to monthly time series

Hello,

I have a timeseries of time against temperature - smallest unit of time is hour

I want to interpolate so the month is the smallest unit of time.

How should I use this function to do this?

vq = interp1( x , v , xq )

Thank you

We recommend converting your timeseries to a timetable() object and then using retime()

I have done this but it removes the date column when I convert back to array.

So, I want to use the interp1 function to avoid this data loss.

https://www.mathworks.com/help/matlab/ref/timetable2table.html adds the times back in as a column in the table. Or you can

timeseries(YourTimeTable{:,:}, YourTimeTable.Properties.RowTimes)

to create a timeseries object.
