Utilidades de programación

Evaluar expresiones o funciones de forma indirecta, ofuscar código, establecer temporizadores, gestionar excepciones

MATLAB^® incluye funciones para evaluar expresiones de forma indirecta, proteger el código fuente mediante técnicas de ofuscación, establecer temporizadores para la ejecución de programas y capturar datos sobre errores.

Funciones

Programar ejecución con temporizador

`timer`	Create object to schedule execution of MATLAB commands
`delete`	Remove timer object from memory
`get`	Query property values for timer object
`isvalid`	Determine timer object validity
`set`	Set property values for timer object
`start`	Start timer object
`startat`	Schedule timer to fire at specified time
`stop`	Stop timer object
`timerfind`	Find timer object
`timerfindall`	Find timer object, regardless of visibility
`wait`	Block command prompt until timer stops running

Gestionar excepciones

`try, catch`	Execute statements and catch resulting errors
`MException`	Capture error information
`addCause`	Record additional causes of exception
`addCorrection`	Provide suggested fix for exception
`getReport`	Get error message for exception
`MException.last`	Return last uncaught exception
`rethrow`	Rethrow previously caught exception
`throw`	Throw exception
`throwAsCaller`	Throw exception as if occurs within calling function
`matlab.lang.correction.AppendArgumentsCorrection`	Correct error by appending missing input arguments
`matlab.lang.correction.ConvertToFunctionNotationCorrection`	Correct error by converting to function notation
`matlab.lang.correction.ReplaceIdentifierCorrection`	Correct error by replacing identifier in function call

Temas

Protect Your Source Code

When you share your MATLAB code, the contents are easily accessed, revealing design and implementation details. You can obfuscate or compile your source files.

Schedule Command Execution Using Timer

To schedule the execution of MATLAB commands, create a timer object.

Timer Callback Functions
Handling Timer Queuing Conflicts

Exception Handling in a MATLAB Application

It is a good programming practice to include error checking in your programs to ensure reliable operation under all conditions. You can decide how your programs respond to different types of errors.

Throw an Exception
Respond to an Exception

Create Hyperlinks that Run Functions

Functions that support the matlab: keyword can display hyperlinks, which execute commands when you click the hyperlink text.

Alternativas a la función eval

Aunque la función eval es muy eficaz y flexible, no siempre es la mejor solución para un problema de programación. En muchos casos, se recomiendan enfoques alternativos al uso de eval.
