You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: learn_struct_dbn_reveal.m
    path of file: ./repos/bnt/BNT/learning
    
    the code of the file until where you have to start completion: function inter = learn_struct_dbn_reveal(seqs, ns, max_fan_in, penalty)
% LEARN_STRUCT_DBN_REVEAL Learn inter-slice adjacency matrix given fully observable discrete time series
% inter = learn_struct_dbn_reveal(seqs, node_sizes, max_fan_in, penalty)
% 
% seqs{l}{i,t} = value of node i in slice t of time-series l.

    
function inter = learn_struct_dbn_reveal(seqs, ns, max_fan_in, penalty)
% LEARN_STRUCT_DBN_REVEAL Learn inter-slice adjacency matrix given fully observable discrete time series
% inter = learn_struct_dbn_reveal(seqs, node_sizes, max_fan_in, penalty)
% 
% seqs{l}{i,t} = value of node i in slice t of time-series l.
%   If you have a single time series in an N*T array D, use
%      seqs = { num2cell(D) }.
%   If you have L time series, each of length T, in an N*T*L array D, use
%      seqs= cell(1,L); for l=1:L, seqs{l} = num2cell(D(:,:,l)); end
