Question:How to make augmented matrix?

Greetings, I am trying to make augmented matrix in the form of A, B and F where A is the tridiagonal matrix, B is the vector and F is the non-linear part of the system. I already tried (A,B,F):=augment(X,output='A','B','F'); but it is an error. Can someone help me? Thank you in advance!

 

 

The matrix X is as follows:

 

X:=[[[-lambda/(h^2),-u/(2 h)+lambda/(h^2),0,0],

       [u/(2 h)+lambda/(h^2),-lambda/(h^2),-u/(2 h)+lambda/(h^2),0],

       [0,u/(2 h)+lambda/(h^2),-lambda/(h^2),-u/(2 h)+lambda/(h^2)],

       [0,0,u/(2 h)+lambda/(h^2),-lambda/(h^2)]]];
