The error identifier includes a component and mnemonic. Note MATLAB converts special characters (like \n and %d) in the error message string only when you specify more than one input argument with error.

String errors[edit] There are two ways that you can create a string; use the ' string ' syntax, or type two words separated by only whitespace (not including line breaks), as Another possibility is that you named your m-file with unusual letters for computers. Existing error dialog boxes with the same title are not deleted. 'replace'Replaces the error dialog box having the specified Title, that was last created or clicked on, with a nonmodal error

msgID -- Identifier for warningcharacter vector | 'all' | 'last' Identifier for the warning, specified as a character vector, 'all', or 'last'. Too many elements. warnStruct = warning(state,mode) returns a structure with an identifier field containing the mode and a state field containing the current state of mode. http://darrenmanning.com/error-message/display-error-message-css.html The correct syntax is >> if a == 3 >> end This creates no errors (and you can put anything inside the conditional you want).
