I'm writing a file where I have to present 14 eigenvectors of (column) length 14 in a nice way. So far I have tried with with align* environment, but I'm not getting the desired results. Basically I want to have one row of 7 vectors side by side and a second row of another 7 vectors (or all in one row if space allows), but I don't now how to align them entry by entry so that the vertical lenghts line up.

\setlength{\arraycolsep}{.8\arraycolsep}(see this code) to reduce the column separation by (say) 20%. You can adjust the.8(20%) to suit your needs. Let me know. – Werner Dec 04 '19 at 19:27
