Ah, I saw there is a text in the F1 help. I suspect some of my questions are still valid.
and with octave-4.2.1-w32.zip
Should the octave ubuntu version work at all? I tried last week, but got errors. But maybe its worth another try….

32bit doesn’t help:
- downloaded https://ftpmirror.gnu.org/octave/windows/octave-7.3.0-w32.zip
copy subfolder mingw32 as folder octave
again deleting /bin/octave.exe and /bin/octave.bat
and renaming /bin/octave_cli.exe to /bin/octave.exe
octave window in Rauschzahl.m freezes the same way.
in “most simple example” also. (see attached png)

Hi zhu.
my example above was created on purpose to show the limitations of qs.
I find your systematic test very interesting. I would have thought that the example has no local optima, thus being an easy example.
Hi t_chiba,
could you share a schematic or qucs project file, please?
I did a quick comparison between qs and Dassault cst. Seems ok for me. See attached files.
Also, there is only “AC Voltage source”, “AC current source” and “power source”
Cheers
Carsten

octave is now able to plot text but crashes

Indeed. I just tried.
BTW. The content of the fields “Data Display” and “Data set” are imho not intuitive
*.dpl seems to mean <schematic-name>.dpl
and in the case, that you described, the field stays just empty.

I don’t have a better solution though

I just posted a reply, but it does now show up here.
It contained weblink, which usually leads to “post is moderated …..”. This message was not shown now, though
probably good idea to copy the whole F1 help file to some text editor with some spell checker, microsoft word, gmail or something. That should find most of these typos.
Should I try it with the newest wine? I used 6.. Wine7 is already out.
FYI: Its not a problem with builtin wine dlls. Issues remain if I switch to native dlls.
Thank you Enki. Meanwhile, Michael sent me a preview executable, which solves the issue.
So another donation? 🤔🙂
I guess questions like the “apply optimized…” could be implemented later. necessary would be e.g. to make xy.opt an array with the size of the parameter sweep. I just don’t know if this would mess up your code base. Somebody could also probably come up next with another still unsupported combination of tasks. And of course, these things can probably be done with matlab/octave “from the outside”.
Still, a scenario like above seems to me like a nice feature that could be useful for others. Me, however would be glad to have it.
not quite.
In my design, there is no formula to calculate the component values from the sweep variable. It needs to be an arbitrary lookup table. You can do this with the “list” in the parameter sweep block. But only for one parameter.
I would like to do something like the one attached. But if I runt it, QS complains
Error in ‘Eqn2’: Wrong index for ‘c_vec’ in equation “c_vec[setup]”.
Error in ‘Eqn1’: Wrong index for ‘r_vec’ in equation “r_vec[setup]”.-

24. November 2022 at 21:36 in reply to: How to use ‘frequency’ as a parameter in an equation block #6814Something interesting about the lossy_inductor.sch:
One can use the variable ‘freq’, which seems to be defined by QS itself. But only, if the equation block has Export=no and if the resulting parameter is used in a “equation based component in frequency domain”
Sadly I cannot find a reference to this ‘freq’ variable in the QS F1 help .You could define all components in the coilcraft model by a separate “equation based component in frequency domain”. Writing down the e.g. z parameters of a capacitor/inductor/resistor should be easy. But maybe its problematic in case you want to use the resulting inductor model without ground connection on either side.
Coilcraft also offers touchstone file models. Maybe that’s an option.
