[Octave-bug-tracker] [bug #65008] ind2sub with indices lower than 0

[Nicholas Jankowski]

Follow-up Comment #2, bug#65008 (group octave):

I would imagine maybe it is supported because you could try to do general
location arithmetic using sums of those indices, but I haven't done it.  What
i do notice looking at their public help is that while they do specify the
array size be restricted only to positive integers, they make no such
restriction on the index input:


Input Arguments

sz — Size of array
vector of positive integers
Size of array, specified as a vector of positive integers...

ind — Linear indices
scalar | vector | matrix | multidimensional array
Linear indices, specified as a scalar, vector, matrix, or multidimensional
array.
