The variables can be defined as 8/16/32/64-bit unsigned integer depending on the size of the data to be stored in the variable. characters. cool but you dont get to use num2str do you? I just realized why I was having so much trouble - in MATLAB you can't store strings of different lengths as an array using square brackets. To create text using one of these words, append a backslash It's unclear whether you're working with numeric or text values. thanks, this is definitely simpler, but the exercise specifically asks you to build functions and to have them pass variables back and forth. As we can see, the output has values that are derived from multiple variables. Thanks, this is very useful. To include numeric variables in the text, use the num2str function. 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. z must be equal sizes.
