Origin Ver. 9.1 and Service Release 3(Select Help-->About Origin):
Operating System: Win 7
Hello everybody,
I am trying to find the index in a list of date-entries that contains the "largest", i.e. "most current" date.
When I am applying xindex for this task, it fails somehow, see screenshot.
Applying xindex on the corresponding Julian date number works as intended.
Is there a method, that avoids the second col to be created? Thanks

Ok,Ok.
From the docs:
http://www.originlab.de/doc/LabTalk/ref/Xindex-func
vd must be a designated Y dataset.
The Y dataset name must correspond to an actual Y dataset.
The associated X dataset must be sorted in ascending order.
Missed that..., sorry. |

Just for the protocol:
What seems to be a possible solution for the original task is:
range aaa = col(a);
maxa = max(aaa);
vfind ix:=aaa value:=maxa ox:=targetindex_dataset;
targetindex = targetindex_dataset[1];
So vfind is the solution her.
Care needs to be taken, when using the output variable targetindex_dataset, as this is a dataset type.
When, e.g.
col(a)[targetindex_dataset] is called, this might yield to errors, while
col(a)[targetindex] should work.
