How to loop time ( hours and minutes ) in a data set

Hi all,

I am working with a 264,xxx *12 dataset, I imported them to matlab as column vectors due to the nature of the sampling the intervals range from 5 to 30 seconds in a 4 hour span for example 6 to 10 pm. I want to achive two things A) be able to average the observations to the minute, b) be able to do a time series graph between y1...y4 vs x(time). My question is where I can find information to do this on matlab?

Thanks in advance

The retime function (and the timetable creation that is necessary to use it) is likely the best option.

Quick question, do I have to get rid of the nans? I ask becuse each interval I have a nan, the resulting table from retime is just nan's all over the place

The fillmissing function may do what you want. Also note that the retime method argument has the ability to fill missing data. I have no idea what your data are, so I can’t make specific recommendations beyond these.
