You have a number of ways to create exceptions based on application conditions. The easiest way is to use the error() and warning() functions. The first creates an error condition, while the second creates a lesser, warning condition. This example presents a basic method of issuing an error or warning due to user input. However, you can use the same technique whenever an error or warning condition arises and http://www.dummies.com/programming/matlab/how-to-create-error-and-warning-messages-in-matlab/ you can't handle it locally. function [ ] = ErrorAndWarning( ) %ERRORANDWARNING Create Error and Warning Messages % This example shows how to create error and warning messages. NotDone = true; while NotDone try Value = input('Type something: ', 's'); switch Value case 'error' error('Input Error'); case 'warning' warning('Input Warning'); case 'done' NotDone = false; otherwise disp(['You typed: ', Value]); end catch Exception disp('An exception occurred!'); disp(Exception.getReport()); end end end The example begins by creating a loop. It then asks the user to type something. If that something happens to be error or warning, the appropriate error or warning message is issued. When the user types done, the application exits. Otherwise, the user sees a simple output message. The example looks simple, but it has a couple of interesting features. The following steps help you work with the example: Type ErrorAndWarning() and press Enter in the Command window. The application asks you to type something. Type Hello World! and press Enter. You see the following output: You typed: Hello World! The application asks the user to type something else. Type warning and press Enter. You see the following output: Warning: Input Warning > In ErrorAndWarning at 16 Notice that the message doesn't say anything about an exception. A warning is simply an in

With the crank's length as r2 and the slider's as r3, matlab error message my code went like this: if r3= mex generates an error. Error: An error occurred writing to file "filename": reason. The file could not be written. The reason is provided by the operating system. For example, you may not have sufficient disk space available to write the file. Error: Cannot recompile M-file "filename" because it is already in library "libraryname". A procedure already exists in a library that has the same name as the M-file that is being compiled. For example: mcc -x sin.m % Incorrect Error: Cannot write file "filename" because MCC has already created a file with that name, or a file with that name was specified as a command line argument. The Compiler has been instructed to generate two files with the same name. For example: mcc -W lib:liba liba -t % Incorrect Error: Could not check out a Compiler license. No additional Compiler licenses are available for your workgroup. Error: Could not find license file "filename". (Windows only) The license.dat file could not be found in
