I dont know a thing about SPICE code or what a resistive crossbar is

using Chatgpt and vibe coding project files: Project files

below is the fixed resistances for the crossbar

X

so the resulting output currents represents the product of the 4x1 input vector and the 4x4 weight matrix (dot product)

resulting currents = (4x1 input vector) X (4x4 weight matrix)

using the code of ChatGPT is:

​now how do I demonstrate it?
