[Octave-bug-tracker] [bug #65616] complex sorting should be only for complex numbers

[Rik]

Update of bug #65616 (group octave):

                  Status:                    None => Wont Fix               
             Open/Closed:                    Open => Closed                 
        Operating System:       Microsoft Windows => Any

Follow-up Comment #4:

Matlab and Octave distinguish complex arrays from real arrays and use the
appropriate sort algorithm for the array type.  Note that the decision on
which algorithm to use is made based on the array itself, and not portions of
the array which may or may not be complex.  This behavior will not be changed
unless Matlab should decide to behave differently.

If you really must have the sort algorithm depend on whether a row is complex
then extract each row and sort it individually.

Sample Code:


x = [1 0 -1; 0 1+0.001i -1];  # Sample data

sz = size (x);
nr = sz(1);
y = zeros (sz);
for r = 1:nr
  y(r,:) = sort (x(r,:));
endfor


This isn't guaranteed to be particularly fast if your array is very large.
