in reply to Re^3: How to iterate through a PDL piddle?
in thread How to iterate through a PDL piddle?
- dog returns a list of PDL slices, as Dima says, so a 2,3,4 ndarray dog-ed would return 4 ndarrays each dimensioned 2,3 (and as they're "slices", updates to them would be reflected in the original ndarray)
- list returns the ndarray flattened (so the whole thing in a single flat list) as Perl scalars, so a 2,3,4 would be a list of 24 Perl scalars
- unpdl (as of 2.006 from 2013, as provided by the mighty Joel Berger), which returns the ndarray as an array-ref with the same (possibly nested) structure as the input ndarray.
