Accessing the elements of Tables that are stored in Lists

Question

I have a list of Tables

Psilist = {psi0, psi1}

Where psi0 and psi1 are 2D tables. I would like to be able to call a specific element of the table in a specific element of the list. e.g. call element [[2, 2]] of the table in Psilist[[2]].

I have already tried

Psilist[[2]][[2, 2]]

as well as using a dummy variable. I want to store the tables in a list as I need to iterate through various time-steps and to do this need to use values from the previous matrix. Any solutions or workarounds would be appreciated.

Answer 1

What you tried should work. Without your full code, we cannot tell why you are having a problem.

Clear["Global`*"]

(psi0 = Array[p0, {3, 3}]) // MatrixForm

(psi1 = Array[p1, {3, 3}]) // MatrixForm

Psilist = {psi0, psi1};

Psilist[[2]][[2, 2]]

(* p1[2, 2] *)

Which is equivalent to

Psilist[[2, 2, 2]]

(* p1[2, 2] *)
