This step is really a jump of faith to me. I consider K(L) as a function that takes L as an input and outputs another function. However, here, the K is considered like a matrix. I do not know why K and L can be separate and do this kind of operations.

Based on previous slide, K is combination of relection operator and transport operators of high order which we can think of a way to represent them as matrix.
