[Octave-bug-tracker] [bug #65018] failing unit test "bug 40117"

[Hartmut]

Follow-up Comment #5, bug#65018 (group octave):

When I copy the exact code from comment #3 into an m-file (I named it
demo_quiver.m) and then run it on my machine, I do get the following error:


>> demo_quiver

quiver example 1:
 clf;
 [x,y] = meshgrid (1:2:20);
 h = quiver (x,y, sin (2*pi*x/10), sin (2*pi*y/10));
 title ("quiver() plot w/arrowheads (default)");

error: 'scripts' undefined near line 3, column 1
error: called from
    demo_quiver at line 3 column 21


This is a different error, than mentioned in comment #3.

When I instead copy the code from comment #3 directly into a (GUI) Octave
console, then I see this error:


>> demo ("quiver", 1)
quiver example 1:
 clf;
 [x,y] = meshgrid (1:2:20);
 h = quiver (x,y, sin (2*pi*x/10), sin (2*pi*y/10));
 title ("quiver() plot w/arrowheads (default)");

>> ## In another terminal window, execute 'touch
>> scripts/plot/private/__quiver__.m
error: 'scripts' undefined near line 1, column 1

 title ("quiver() plot w/arrowheads (default)");

>> quiver example 1:

I hope this helps. Let me know if I should run different code on my machine.
