I had never put anything on math overflow before and I have taken this opportunity to try it.

Do you know these matrices described by Alan Rendall? If so, please point out a source where he may find more information about them. I am interested in knowing too!

There is nevertheless a non-trivial intersection between the matrices I was interested in and the Toeplitz ones and so there might be something to be learned in that direction.

It could perhaps be viewed as the Laplacian matrix of a weighted directed graph (this graph would be a 1-dimensional “chain” where the “last” vertex has an outward edge incident on the “first” vertex).
