Re: [arts-users] Extract element from vector
Dear All,
Thanks to Jana and Oliver for their help.
Jana is correct: I could probably do this without using the batch agenda; I do
not think I am doing anything which fundamentally prevents this. But I could
not work out how to do that either . I will probably try to sort that out at
some point.
Meanwhile, Oliver's hints have enabled me to get it working by using the batch
agenda.
Best wishes,
Hugh

Hi Hugh,
you are probably doing things in the batch agenda, that make you require or
prefer a batch agenda. But if it's just about multiple LOS - they can also be
done in a single, non-batch run (that's why sensor_los is a matrix; one of it's
dimensions is the number of LOS, or in a more general way the "number of
measurement blocks" as the doc calls it).
Best wishes,
Jana

The relevant bit of my control file goes:

}
But I get an error in the Extract() method which says:
Workspace variable belongs to the wrong group: my_loses is not ArrayOfMatrix,
it is Vector
At the root of this is that sensor_los is a matrix, even though it has only one
element. I have tried a few other combinations of creating a matrix instead of
a vector and/or using Select() instead of Extract() to extract a value from it.
Select() was no good because ybatch_index is an index, not an array of index.
What am I doing wrong? How do I create a 1-D array of numbers which Extract()
will extract a single value from? I am sure I am being really dim here :-(

Re: [arts-users] Extract element from vector
Hi Hugh,
Since ARTS is strongly typed, a Numeric cannot be assigned directly to a Matrix.
But you can extract it into a temporary variable and then use MatrixSetConstant:
Arts2 {
VectorCreate(my_loses)
VectorSet(my_loses, [180,170,160,150,140,130])
Print(my_loses)
IndexSet(ybatch_start, 0)
IndexSet(ybatch_n,6)
NumericCreate(one_los)
AgendaSet(ybatch_calc_agenda){
Extract(one_los,my_loses,ybatch_index)
MatrixSetConstant(sensor_los, 1, 1, one_los)
Print( ybatch_index, 0 )
Print( sensor_los, 0 )
## Actual calculations including iyCalc go here
Touch(y)
Touch(y_aux)
Touch(jacobian)
}
ybatchCalc
}
Hope this helps.
Cheers,
Oliver

[arts-users] Extract element from vector
Dear ARTS gurus,
I am trying to use ARTS's batch feature to do calculations for a range of

Extract(sensor_los,my_loses,ybatch_index)
Print( ybatch_index, 0 )
Print( sensor_los, 0 )

}
