The problem seems to mainly be on line 46 because comparing two cell arrays is not supported in strcmpi. I believe there is a simple fix: Use ismember instead of strcmpi (and add lower so it's still case insensitive):
varToMatchA_idx=find(ismember(lower(obj.demoTable.Properties.VariableNames),lower(obj.varToMatch)));
This fix requires two additional changes.
On line 59, capture the case where obj.varToMatch is a cell containing only one column name:
if ~iscell(obj.varToMatch) || length(obj.varToMatch)==1
On line 76 expand the obj.varToMatch cell array. (Lines 59 and 72 already require that obj.varToMatch is a cell array already to reach this point).
T = cell2table(data(i).demographics(obj.varToMatch{:}),'VariableNames',varToMatchA);
