Am I missing something or is this just a linear transformation?

It says here ( https://www.researchgate.net/publication/370980395_A_NEURAL_... ) that each layer can be represented as a matrix multiplication (equation 3): Ax = s

So concatenating multiple layers could just be reduced to a single matrix multiplication?

If there is no non-linearity I don't see how this could replace neural networks, or am I missing something?
