Giles Atkinson c65155880c Make "nogrid" plotting option work. The deleted code was in the original 
commit, so the reason for it can not be traced.

Giles Atkinson b0798cf70e Make Mac and Linux build scripts executable. 2022-04-26 10:32:32 +02:00
Holger Vogt 26c50de68b function deriv: This is just a preliminary fix: prevent a crash 
when base > 0.

But when is base supposed to be > 0 ? More invetigation is needed.

Holger Vogt 5c0b41d277 Update to config.h 
Move relevant entries up to the top of the file

S-parameter and periodic steady state may be selected in config.h

CIDER and XSPICE are always selected and cannot be excluded
(will not compile without).

Holger Vogt 12a93c9fe6 Update to plotting of event nodes: 
Distance is now 1.5, scaling and cutouts are possible
(with some lack of precision).

Still missing: y axis labeling (no numbers, but node names).
 2022-02-21 20:19:56 +01:00
Holger Vogt 342a16d6e1 Add a flag 'alle' (all event nodes) to the plot command (and maybe others). 
All event nodes with length greater than 1 are translated to vectors
with a common scale (named step) and are assembled in a new plot
named 'digital'. They may be plotted or otherwise used in a
.control section.
