- Create two timetables using table2timetable (you have to converted the time to duration or datetime format)
- Use synchronize OR retime with a common time vector.
Interpolate and synchronize two time series

Hello,
I'm trying to match two different timeseries to one common time-vector. The problem is, there are two matrices which I want to match. First of all I'll give an example:
matrix_A
TimeA DataA_1 DataA_2 DataA_3
0.27 63 57 12.3
0.31 65 47 11.3
0.54 69 53 11.7
0.82 71 51 11.9
0.98 70 52 12.1
1.24 69 49 12.4
--------------------------
matrix_B
TimeB DataB_1 DataB_2
0.13 113 23.7
0.54 112 25.8
0.69 110 24.4
0.85 115 23.5
1.03 113 25.9
Now i want to match this two series of data to one matrix with equal time gaps, for example 0.25.
My idea is: First interpolate both data-series to get values at 0; 0.25; 0.5; 0.75; 1.0; 1.25 ... and then safe them in one single matrix, that looks like:
matrix_finish
Time DataA_1 DataA_2 DataA_3 DataB_1 DataB_2
0 ... ... ... ... ...
0.25
0.5
0.75
1.0
1.25
...
I know, there are functions in matlab like synchronize and interp1 or something, but it looks like I am to stupid to use them correctly for my problem.
Thanks for any help.
