For example, replace the calls to fprintf with the following: If you happen to be outputting to a terminal emulator (e.g., if you are running matlab -nodesktop) then you may be able to take advantage of the ANSI sequences for text attributes: http://en.wikipedia.org/wiki/ANSI_escape_code#graphics, https://www.mathworks.com/matlabcentral/fileexchange/24093-cprintf-display-formatted-colored-text-in-the-command-window. end The default format is %s\n. if nargin < 2 ...; Another Command Window text color hack – Matlab's fprintf command has an undocumented hack to display orange-colored text.
