Hello jim, thank you for your quick answer!
Here is an example:
*TIME1* *DATA1* *TIME2 DATA2*
2 14:38:00 1.07212 14:38:00 1.51339
3 *14:40:00 1.07195 14:39:00 1.51330*
4 14:41:00 1.07218 14:40:00 1.51335
5 14:42:00 1.07246 14:41:00 1.51326
6 14:43:00 1.07229 14:42:00 1.51310
7 14:45:00 1.07226 14:45:00 1.51310
8 *14:46:00 1.07205 14:48:00 1.51357*
9 14:47:00 1.07078 14:49:00 1.51375
10 14:48:00 1.07155 14:50:00 1.51359
11 14:49:00 1.07184 14:51:00 1.51406
12 14:50:00 1.07114 14:52:00 1.51458
And I would like to get from this only one matrix, with the matching time
and the corresponding data.
Of course, some rows from one or another matrix will have to be removed.
Thank you very much again for your help!
Loïc.
