Suppose I have a table T about New York with variables a,b,c.... I would like to rename all variables in T as 'NYa",'NYb',.... etc without renaming variables one by one. Please advise.

T.Properties.VariableNames = cellfun(@(S) ['NY', S], T.Properties.VariableNames', 'Uniform', 0);

insertBefore({'a' 'b'},1,'NY') (or strcat('NY',t.Properties.VariableNames) before R2016b-ish, I forget exactly when) would also do the trick.
