But I'm trying to sort variables from highest to lowest and I want to get Matlab to print their corresponding variables rather than just giving me numbers. I want to just have little sections of text that pop up explaining what is happening in the program-and I want these to be displayed in the command window for a user to see. Couple of choice depending upon just how you want to use it As a function, can retrieve the passed variable name with, so can write something like the following (without any error checking, formatting, etc., etc., etc., )--, % DISPWITHNAME(X) -- Display scalar variable(s) in argument list with name(s), Alternatively, you could capture the list of desired variables from, with an argument list including appropriate wildcard and then iterate over that list having rearranged the order from the default aplphanumeric sort to the desired numeric order by use of the optional indexing array variable returned by. The Font size, specified as a scalar value greater than zero in point units. Other MathWorks country For a custom color, specify an RGB triplet or a hexadecimal color code. But after I use the sort command the function only gives me values (from highest to lowest), what im trying to do is to get Matlab to find the corresponding variable name from the value and splay them together.
