At present there is a matlab tag, which in itself is very odd for an electrical/electronics section.
Matlab and an associated tag would naturally reside within Stackoverflow.
Two products that exist alongside Matlab are: Simulink & Simscape. Both, to some degree show some relevance in residing within the electrical stackexchange.
Not only does this stackexchange cover aspects of control & control theory (something simulink & simscape are designed for) but equally are geared towards electrical analysis
Simulink Capacitor doesn't load in simulation
https://electronics.stackexchange.com/questions/193639
PID controller DC motor Design using simulink
and more....
All of these have the matlab tag when in actual fact they are simulink/simscape
Would a simulink and/or simscape tag be of use? It is afterall a system and electrical circuit simulator... its focus is just a bit more abstract from the likes of LTspice/Tina etc...
