Not only that but your idea of calculating the mean of each column separately is waste of MATLAB, which generally works most efficiently on entire arrays at once. Much simpler would be to store the names as data in their own cell array (untested as you did not supply any data): vec = [ 4, 2, 1, 3, 5]; So it sorted the data and names, and then printed them in the command window, exactly as you requested.
