From: Ralph on 11 Mar 2010 14:09 Hallo! I'm setting up some default options with a struct: defaults.color = 'r'; defaults.marker = 'o'; defaults.text = false; A user can now change some of the default option. e.g.: options.color = 'k'; Now I'd like to overwrite the default options with the options changed by the user: finaloptions = Overwrite(defaults, options) Giving: finaloptions.color = 'k'; finaloptions.marker = 'o'; finaloptions.text = false; Is there a function that does this for me or do I have to program it myself? Thanks, Ralph

Because the only thing the user should need to do is to setup those option they want to change. Yes, I could give them the defaults-structure but I don't want to. And yes, it's only cosmetics, I know. Ralph
