Disable detection of bifurcations

*all po constructors

Yes, both syntaxes are correct. This is the meaning of 'log|on', as in logical (true/false) or on/off.

A cursory glance suggests that this should work for all po constructors and I have no reason to believe this is not the case. If you are willing to share your script, I can have a look.

Best,

Hi
Thanks for confirming the syntax.
A quick test with coco/po/examples/hopf/demo.m confirmed that order matters.

prob = coco_prob();
%prob = coco_set(prob, 'po', 'bifus', 'off'); %test 1: OK
prob = ode_HB2po(prob, '', 'ep_run', HBlab);
%prob = coco_set(prob, 'po', 'bifus', 'off'); %test 2: too late

fprintf(...
  '\n Run=''%s'': Continue periodic orbits from point %d in run ''%s''.\n', ...
  'po_run', HBlab, 'ep_run');

bd3  = coco(prob, 'po_run', [], 1, 'p1', [-1 1]);

The error was that I tried to add bifus after ode_HB2po. After putting it in the right place, the bifurcations are no longer detected indeed.

This question can be closed.

Best regards

Or first a follow-up question, still in the file coco/po/examples/hopf/demo.m, where I have added following lines to plot po_run:

figure(2); clf;
thm = struct('special', {{'EP'}});
coco_plot_bd(thm, 'po_run', 'p1', 'p2', '||x||_{2,MPD}')

When po_run has been calculated with 'bifus', 'off', the plotting function gives following error:

Error using coco_bd_col>coco_get_col
coco_bd_col: column not found: 'po.test.USTAB'

Error in coco_bd_col (line 32)
  col = coco_get_col(bd, name, cat_flag);

Error in coco_plot_bd (line 195)
  S   = thm.ustabfun(coco_bd_col(bd, thm.ustab));

Maybe the problem is related to the plotting of stable (full line) and unstable (dashed line) parts of the branch?
What would be the easiest way to still plot the branch corresponding to po_run?
