- To interpolate the values for every minute you can use the INTERP1 function as explained here .
- To calculate the mean values for one year use the MEAN function over the corresponding data. Click here to know more about the MEAN function.
- Similarly use the STD function to compute the standard deviation as explained here .
Irregular (long-)time series is to be interpolated as well mean value and standard deviation to be calculated. How?

Hi all,
I´ve imported data from a .mat file with dates (this format: '2010-02-25 14:49:00', comment:second values are 00 for all dates ) and values (format: 1.23) . Then I converted the date by using datenum() to a number and created a matrix F1 (85888 x 2 double), see below:
734194.617361111 | 0.61
734194.638194445 | 0.57
734194.659027778 | 0.68
. . . .
The Values are from feb 2010 until dec 2015....BUT on irregular time intervalls.
Now I want to
1. interpolate the values so that I have a value for every Minute.
2. cummulate all values to determine the mean values for one single year.
3. calculate the standard deviation over the whole year.
Please assist.
btw: I´m kind a newbee
