Hello,

I have a datetime vector with a size of 140257x1 and have data points with a size of 2178x140257. That means for each point(2178) has a data of time series(140257) in that matrix. So I have 2 different matrix, one of them stores the time and another is data for each point. Normally there is retime function in matlab but it works with tables. Also this is possible with for loop but it is costly.

How can I average my data points matrix daily in a smart way?

Thank you for your time and effort.

I would first transpose the data vector matrix, then use array2table to create a table with the data matrix, then use the addvars function to put the datetime vector as the first variable. Then use table2timetable and then use retime.
