Translate Issue Warnings and ErrorsIssue WarningsYou can issue a warning to flag unexpected conditions detected when running a program. The warning function prints a warning message to the command line. Warnings differ from errors in two significant ways:Warnings do not halt the execution of the program.You can suppress any unhelpful MATLAB® warnings.Use the warning function in your code to generate a warning message during execution. Specify the message as the input argument to the warning function:warning('Input must be text')For example, you can insert a warning in your code to verify the software version:f

I know if a m-file goes wrong at run time we can press Ctrl-C to stop it. but I need a command to put it in my m-file to do so if something bad happens. Please don't suggest 'exit' or 'quit' commands as they terminate the entire matlab and I don't want it. matlab error-handling command share|improve this question edited Jul 4 '12 at 20:11 asked Aug 4 '10 at 18:18 kami 2,01683049 add a comment| 3 Answers 3 active oldest votes up vote 6 down vote accepted You can just put a error command like error('bad user input') and it should stop the script. Edit: alternatively, you could just refactor your code to not run unless you set the input flag to be true. Something like inp = input('>', s) if validateInput(inp) %do you stuff here or call your main function else fprintf('Invalid input') end share|improve this answer answered Aug 4 '10 at 18:22 Xzhsh 1,30311229 If there are multiple places where a function needs to exit, this solution leads to a tree of run it or not kind of if statements.
