Follow-up Comment #1, bug #59709 (project octave):

I have a patch that appears to work for this case.  However, I'd like to
understand how Matlab handles multiple events that happen on the same
timestep.  I'm uploading a new file test_event5.m.  Could someone with access
to Matlab run the following code and then upload the diary file?


diary on
x0 = 5;
maxT = 8;

opt5 = odeset ('Events', @test_event5);
sol5 = ode45 (@myode, [0,maxT], x0, opt5);

sol5.xe
sol5.ye
sol5.ie
diary off
