Routines
top source pp_structsubset
result = pp_structsubset(structin, fields)
Creates a structure that has a subset of the fields from the input structure.
Return value
A structure with a subset of the fields from the input structure, specified by a string array with the field names, in the desired order. If the order of the fields did not matter, this could be done easily with a hash.
Parameters
- structin in required
The input structure, from which a subset will be taken.
- fields in required
A string array with each element specifying the name of a field of structin to go into the output structure.
Examples
Make a simple structure and subset it:
structin={a:18,b:'something',c:[0,9],d:[-9.5d0,4.85d0,17d0]}
help,pp_structsubset(structin,['d','b'])
;** Structure <a413a488>, 2 tags, length=40, data length=40, refs=1:
;D DOUBLE Array[3]
;B STRING 'something'
print,pp_structsubset(structin,['d','b'])
;{ -9.5000000 4.8500000 17.000000
;something}
