I've learned most of what I know on my own using it. If a variable contains an empty array, disp returns without displaying anything. Choose a web site to get translated content where available and see local events and offers. 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. 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. You can use the disp () function to display a string in MATLAB. To change the But, "m" does not look like a mathematical character as it looks neat in latex.
