Hey,

I have been trying to set up a 1D quantum wire and then calculate the conductance. However when trying to calculate the smatrix it gives me the following error:

ValueError: Input needs to be a square matrix.

And my system that I am working with is defined as follows: lat = kwant.lattice.chain(a)

How can I possibly resolve this problem? Or where should I be looking to get an idea?

Sincerely, Binayyak
