How to increase temporal resolution from 3-hourly to hourly data with interpolation?

I have a dataset of temperatures measured at 3-hourly intervals which looks like this:

0   1.37660000000000
3   4.57660000000000
6   3.17660000000000
9   3.67660000000000
12  6.07660000000000
15  11.2770000000000
18  4.97660000000000
21  3.37660000000000

I want to upgrade the temporal resolution from 3-hourly to hourly with interpolation in between the data points.

For example:

0   1.37660000000000 <= original value 
1   2.44326666666667 <= linear interpolation
2   3.50933336666667 <= linear interpolation
3   4.57660000000000 <= original value
4   4.10999999999993 <= linear interpolation
5   3.64326666666667 <= linear interpolation
6   3.17660000000000 <= original value

How can I do that? Thanks!

If the Signal Processing Toolbox is available, the easiest way to do that is with the resample function.
