Holger Vogt ae221a70c2 Remove a typo: runable --> runnable 2022-04-15 10:52:56 +02:00
Holger Vogt b7ae16838a Make SP (S-parameter) standrad during compile. 
The configure flad --disable-sp will remove SP

Holger Vogt cd01f4949e Make error message more verbose 2022-04-11 12:05:54 +02:00
Holger Vogt 9deb9f51d8 In case of resistor valuues r150 (r + integer number), 
return 150
R2 n1 n2 r150

In case of r23mod return error = 1 and val = 0, so
r23mod may be read as a model, not an instance parameter
R3 n3 n4 r23mod

Giles Atkinson e16564edf7 Make "nogrid" plotting option work. The deleted code was in the original 
commit, so the reason for it can not be traced.

Holger Vogt df9859a5d0 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.

on Linux.
Setting terminal here is redundant, so remove this setting.

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.
