Matlab Data-series conversion

Hello,
I Have been trying for the past couple of days to convert a time-series data-set but, unfortunately, with no results.
I have attached an extract from the excel file. The first row is date and time (together) and their respective temperatures taken every 10 minutes. The problems with this are three: the first it that the dataset is not contiguous (ie sometime there are holes where the data were not recorded for a certain amount of time) the second is that I would need a contiguous series where if a day was not recorded the time would still be 'flowing' and the temperature would be indicated as missing. The third is that I would need an hourly series instead of a one every 10minutes.
Would any of you have any ideas?
Thanks John

Have you looked at using interp1()?

Why is that a problem? Interpolation will estimate them for you. Pass in what you have, and ask for what you want and you'll get it.
