Do you by any chance have an assembly I can set up that exercises this?
Yes—strictly-zero eigenvalues actually seem to turn up often. As an example, go to the General test assembly, set…
I guess we don't need an on-screen or README/other doc-file reminder that the positive eigenvalues are the blue dots and the negative ones the green squares?
I could start a wiki page that…
Well, the easiest way would be to show a symbol (or numeral giving multiplicity) in a different color or something like that, at some reasonable offset below the smallest nonzero eigenvalue.
D…
(E.g., if we're using a wonky log-scale feature of the plotting software at the moment, maybe we could just take the logs ourselves and give the data to the plotter as log values to be plotted…
This is to protect us from trying to display exactly-zero eigenvalues, that have no log?
Yes. Trying to display eigenvalue which are too close to zero seems to throw off the scaling procedure…
I decided to include the scale change we discussed on Monday in this pull request. It's implemented in commit fa39a9a. As proposed, the Spectrum chart now splits the spectrum of the Hessian into…
The packaging script on the [Vectornaut/dyna3:demo-summer-2025](https://code.studioinfinity.org/…
Done on the Vectornaut/dyna3:demo-summer-2025 branch, as of commit [40f35ea](https://code.studioinfinity.org/Vect…
I'm removing the dependencies on the following issues:
- #66 because we decided that loading an assembly from a file would amount to calling a sequence of element and regulator creation…
Note that a first PR would presumably only implement the core of the features listed above; its merge should be accompanied by filing issues with the remaining desired features and resolving…
