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: or.m
    path of file: ./repos/d4m/matlab_src/@Assoc
    
    the code of the file until where you have to start completion: function AB = or(A,B)
%|,or: Performs logical or of two associative arrays; output value is the min of the two input values.
%Associative array user function.
%  Usage:
%    AB = A | B
%    AB = or(A,B)
%  Inputs:
%    A = associative array
%    B = associative array
%  Outputs:
%    AB = associative array that is the union of the keys of A and B

  % Deal with value type mismatches.
  if ( not(isempty(A.val)) && not(isempty(B.val)) )
    % OK.
