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: printSetup.m
    path of file: ./repos/chebfun/@chebguiExporterBVP
    
    the code of the file until where you have to start completion: function printSetup(fid, expInfo, guifile)
%PRINTSETUP   Print commands for setting up problem.
%
% Calling sequence:
%   PRINTPOSTSOLVER(FID, EXPINFO)
% where
%   FID:        ID of a file-writing stream.
%   EXPINFO:    Struct containing information for printing the problem.

% Extract info from the EXPINFO struct:
dom = expInfo.dom;
deString = expInfo.deString;
deInput = expInfo.deInput;
bcInput = expInfo.bcInput;
initInput = expInfo.initInput;
allVarString = expInfo.allVarString;
allVarNames = expInfo.allVarNames;
indVarNameSpace = expInfo.indVarNameSpace;
periodic = expInfo.periodic;
useLatest = expInfo.useLatest;

% Print commands for problem set-up:
fprintf(fid, '\n%%%% Problem set-up.');
fprintf(fid, '\n%% Define the domain.\n');
fprintf(fid, 'dom = %s;\n', dom);
fprintf(fid, ['\n%% Assign the differential equation to a chebop on that ' ...
    'domain.\n']);
fprintf(fid, 'N = chebop(%s, dom);\n', deString);

% Setup for the RHS
fprintf(fid, ['\n%% Set up the rhs of the differential equation so that ' ...
    'N(%s) = rhs.\n'], allVarString);

% If we have a coupled system, we need create a array of the inputs:
if ( size(deInput, 1) > 1 )
    deRHSprint = '[';
    for counter = 1:size(deInput,1)
        deRHSprint = [deRHSprint num2str(0) ';']; %#ok<AGROW>
