It would be useful to be able to see the current values of these variables. It is not useful to print them, because other parts of the loop are printing a lot of text. Also, on the Workspace tab, the values do not display until the end of the loop.Using this, you can create a short function that, given a variable, will output the name of it as a string, as in the following example: Theme. Copy. function out = getVarName (var) out = inputname (1); end. As long as the file is included on the MATLAB path, you can use the function in the following way: Theme.
