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

조회 수: 8 (최근 30일)
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.
